Learning How To Think Better

The more I work, the more I realise that the strategic thinking and problem solving skills are more valuable than writing several lines of code in Java/Kotlin/Groovy/Javascript/Python. Ironically, many software developers (myself included) put so much time into improving coding skills without dedicating enough, if any, time towards learning how to think more efficiently. Sure, our thought processes naturally evolve with time and experience, but this generally comes only as a by-product of professional growth.

Reading ‘Pragmatic thinking and learning’ motivated me to put conscious effort into learning how to make better use of my brain. I’ve tried different suggestions from the book, and these particular ones have worked well for me:

  • Motivating the brain to produce more ideas
  • Learning to engage the creative part of the brain


Motivating the brain to produce more ideas

Most of you would be familiar with an exercise called “brainstorming” when people sit down and try to crunch out some ideas. But our brains do not really need a ritual to produce ideas — it happens naturally, at random times throughout the day. I believe that with time as our minds get more and more occupied with various issues, our brain’s idea generating channel effectively gets muted. I now try to capture all the ideas (usually on paper — here is why) and random thoughts that pop into my head. I imagine it as training a puppy — whenever a puppy behaves well, it gets a treat. In this case a puppy is my brain, good behaviour is producing an idea (any idea) and a treat is the fact that I acknowledge and write it down. This motivates the brain to produce more and more ideas.

I advise having a place — document, spreadsheet, mind map, board, etc — where you can store your ideas long term. For me a Trello board has been working great for years:

Roughly once a week I go through the pile of ideas that I’ve gathered. Some of them (maybe even most of them!) go straight to trash, some I refine and keep in the ‘ideas’ section for another week, and some are good enough to be moved to ‘to do’. It feels like gathering lego blocks for the whole week and then looking through the pieces to see if any of them can contribute towards building my future.

By doing this I felt like I was letting my subconscious thought process know that I acknowledge and appreciate all of its hard work. With this positive reinforcement, I noticed that every week I had more and more ideas. In the end, who does not like to be acknowledged?


Engaging the creative part of the brain

Involve the senses

Here I talk about different modes of the brain — one is our conscious way of operating (L mode) and the other one is a free-spirited unconscious source of creativity (R mode). The best results happen when there is a stable connection between the two, the question is how to create, maintain and make this connection stronger.

Our senses are our friends here. Did you notice that some people fiddle with a pen or something of that sort when they are thinking? It is fun to do, but it serves a more important process — an increase in sensory input stimulates our R-mode (in other words — creativity). I’ve noticed that many chess players fiddle with pawns and pieces while playing — for example, check out this game between the World Champion Magnus Carlson and one the best players in the world Daniil Dubov: https://youtu.be/xo24b3wH8K4?t=14.

Using cross-sensory feedback stimulates the creative part even more. You can write an idea/design down, draw a visual representation of your thoughts, try to describe the problem out loud, or try to argue the point from different angles (maybe even involve your colleagues). You could go as far as acting out the roles involved, which for me makes the thinking process simply more playful and enjoyable.

Letting the mind flow

I have a habit of getting completely submerged into my job. It helps me to a great extent with my career but also has a big impact on other areas of my life since I barely stop thinking about the work problems. Be it a technical challenge or figuring out how to grow our engineering department or how to reduce our turnover rate — all of these problems are captivating and fun to solve; however, I realized that I started to slowly abandon an unrestricted, free-flowing state of mind. I believe it is absolutely critical to give our minds opportunities to be in that state so it can de-clutter, re-organise and simply rest from all the conscious thinking that is enforced on it. But how do we get there?

I was extremely skeptical about it at first, but simple 30–60 minute walks have become an inseparable part of my daily routine. The main rule is to not have any agenda for these walks, so going to get groceries does not count! By having no agenda, I simply focus on soaking in the surrounding environment (sights, sounds, weather, etc) and this frees up my mind to flow. Then I feel like a kid who tuned in to some random radio station and is curiously trying to figure out what the broadcast is about.

Taking a stroll down a colourful street

After the walk I generally feel refreshed and ready to take on the rest of my day. My stress level is reduced, I’m happy that I did something that is good for my health and my mind feels (even if a tiny bit) rejuvenated.

I hope that my experience spurs some questions in your mind and maybe even helps you. If it does — I’d happy if you reached it and shared your story with me!

國師防疫二十問,中港尋死效普京

 

圖:尖沙咀彌敦道的遊客區柏麗大道,行人稀少,店鋪倒閉。


香港一半人口感染,還要安心出行和疫苗通行證來做什麼?

安心出行目前已經default(設定)了不再追踪,還要來做什麼?

全世界都在取消疫苗通行證,只有香港繼續做到年底,去理髮店剪個髮,去街市買棵菜,要拍兩道身體特徵的認證卡(疫苗證是身體特徵記錄),好像在進入美國五角大廈國防部,目前是香港政府刻意要妨礙人權和破壞經濟給海外投資者看嗎?

根據港大醫學院的推算,430萬人感染,政府的推算也差不多這個數目,請問超過一半香港人口感染的情況下,要安心出行來追踪什麼?港府可以回答嗎?


另外,超過九成香港人打了第一針,而omicron變種病毒株對於老年以外的群體是病癥輕微,可以在家休息一兩日就康復,只要感染了就是自然免疫,請問香港目前超過430萬人感染了而獲得自然免疫,還逼人打疫苗做什麼呢?

政府有了美國口服特效藥對付重症,而輕症根本是弱感冒症狀,還打針來做什麼呢?

嫌香港人長命拖垮福利嗎?

要副作用和後遺症來危害某些人民嗎?

要孕婦流產嗎?

要小孩和學生失學兩年來降低人才供應嗎?

要整死小孩令某些一孩家庭絕後嗎?要急性癌症和心肌炎和其他疾病來逼死香港人嗎?

一個家庭支柱死了之後,政府除了送棺材殮葬之外,是否準備福利負擔全家老少呢?

香港的經濟損失和生產力破壞,香港政府是否可以啟用現代化和AI來取代呢?

香港政府有不想要那麼多人口的產業轉型計劃嗎?


更不用說,這種疫苗通行證如何破壞中小企業生計,令到香港遍地哀鴻,到處是倒閉的百年企業和店鋪。港府是否撥備了失業金和企業貸款幾年呢?

香港政府是可以自主發鈔和QE的主權國家嗎?是嗎?


現在馬來西亞政府都嘲笑中國政府是世上唯一的防疫笨蛋。我呼籲香港政府面對現實,從速取消安心出行,取消疫苗通行證及打針要求,那只是製造人民鬥爭和企業內部勞資分化,逼走機構裡面有資歷有骨氣的team member,除了破壞香港人民內部團結和毀掉本地機構的team spirit之外,毫無醫學意義和公共衛生作用。

要玩弄人民的,玩夠了,要收集數據的,收集夠了,要逞淫威的,逞夠了。收手吧!為了不攬住一齊死,請香港政府收手吧。否則,香港人只能用改變居留地的方式來改變自己的命運,跺下腳上的塵土,離開索多瑪和哥摩拉,將香港留給經濟蕭條和人民憤恨的怒火來燒掉,很多香港人——包括在下,是對政府兩年來的所作所為絕望透了。

我希望傳媒可以在特首記者會提問這些關乎香港生死存亡的和人間正義的問題,否則香港媒體可以全部執笠,它們兩年來在防疫上毫無發揮平衡意見和傳播醫學新知的作用。


普京好戰尋死,中國防疫跟隨?


中國和香港的防疫暴政,與普京要攻打烏克蘭一樣,完全違反一切理性決策,完全違反一切民族利益,而且令國際孤立和困鎖,怎樣勸也勸不回來。你能找到理性嗎?例如普京說烏克蘭如果答應承認克里米亞的主權歸俄羅斯、烏克蘭東部兩個省宣布獨立,他就撤兵,然而這不是他發動戰爭之前就是這樣的嗎?勞師動眾,殺人千萬去取一些本來就在手上的成果,普京是瘋掉了。但我們中國呢?能比普京聰明一點嗎?

普京我勸了幾個月,中國和香港,我勸了兩年半。他們都是一往無前,走入地獄門。

這是一個民族的死亡衝動,death drive,thanatos。也是天命該絕了這兩個在近代作孽深重的民族。儒家說的天人合一,不是口頭禪,是實實在在的道理,大家現在見到。

港府防疫政策急轉彎,國師貼文起了作用;香港是大都會社區,小區封城是笑話

 


正當我要煩惱幾時才有得理髮的時候,政府今日下午五點半公佈,理髮店或髮型屋將可獲准在本周四(3月10日)重開,惟須全面實施「疫苗通行證」,進入或身處有關處所的人士須至少接種1劑新冠疫苗。原先政府還鐵口錚錚,說要4月20日才考慮重開的,想不到後日就開了。

是我昨日在面書貼文和Patreon的文章起了作用啊。政府與內地專家梁萬年教授開會之後,大幅度調整抗疫政策。現階段要做得是照顧重症和地方年老者轉成重症,全民檢測不是最優先的工作。之前,梁教授說要「綜合考慮」依照大陸官場的語言,即是不必做。政府已經建立平台給予自行申報陽性測試反應者。申報情況踴躍,因為可以請病假幾日。


「全民檢測」終於變了「傳聞檢測」

港府在過去一個周末和國家衛健委新冠疫情應對處置工作領導小組專家組組長梁萬年開會後,正醞釀大幅調整抗疫策略,梁萬年提出要減感染、減重症、減死亡,其中最優先的將會是減少死亡,這會是現階段工作的重心,會在治療方面加大力度,盼一兩周有效果,其次是減重症,之後是減感染;現階段全民強制檢測不是最優先的工作。全民強檢方面,早前有報道將於3月26日進行,並可能會配合「禁足令」等要求。不過據本地傳媒報引述消息人士報道,模型推算本港或已有兩成人染疫,看來政府未必會執行。我在新年前,1月23日於面書貼文及在youtube拍片呼籲政府不必全民強制檢測,可以改為自願測試和自願申報方式,用抽樣(sampling)的方式推算感染情況,看來現在政府有聽取意見。

自由亞洲電台認為,過去一星期平均數顯示,香港死亡率激增3倍,是已發展地區中死亡率最高,甚至超越英、美、韓國、新加坡及台灣等地,截至周日(3月6日),以每百萬人口計,香港的死亡人數為25.5,美國是4.28,韓國是2.89,新加坡是1.86,日本是1.68。傳媒認為香港死亡率高,是因為長者的疫苗接種率低。筆者認為,這是香港清零隔離兩年,之後用檢測排隊的方式達致感染高峰,將兩年的死亡人數放在兩個星期而造成的統計學幻象而已


感染已過高峰期,口服特效藥已經引入香港公立醫院

港大醫學院就本港新冠病毒疫情發展進一步推算研究,預測截至2022年5月1日,第五波疫情總感染人數為430萬人,總死亡人數為5008人。每日新增感染人數於3月4日已達頂峰,預計於4月23日首次降至三位數,即1000人以下,從5月中旬持續穩定在2位數,即100以下。由於感染數字達到高峰之後回落,而死亡及重症受到控制,故此已逐步達到群體免疫,有條件與病毒共存,沒必要繼續加強防疫

目前香港已經引入美國默沙東藥廠的Molnupiravir,首批藥物已於上月底到港。美國輝瑞的口服特效藥Paxlovid將於3月底前抵達香港。如果臨床效果顯著可以減低重症及有效在家服用治療,那麼隔離營無須使用,也不必再脅迫注射疫苗,因為已有特效藥,而使用mRNA技術的輝瑞疫苗的眾多後遺症也被美國FDA在法庭判令下提早於3月1日公佈。

全民檢測不可行,「小封區」無視香港區域自治已變

在3月2日,特首林鄭月娥不會封城檢測,但小封城、小禁足是會考慮做。這是昧予時世之言,她彷彿是活在香港的上世紀七、八十年代。

一年前,小封區在法國、德國、意大利等地都做過,因為當地的區(德國的Gemeinde和法國的communauté)都是自給自足的,裡面工作的法官、教師、警員、醫護人員、藥劑師、屠夫、銷售員、農夫等等都是同區的,他們跨區換了工作就租屋去當地住,故此這些區可以做防疫封區,不會有問題。筆者以前在德國遷居,都被要求去警察局消戶口和報戶口,我問官員為何要好似社會主義國家那樣記錄戶口,官員說,要觀察市鎮的人口,並且保證當地有足夠的醫生、藥劑師、教師、廚師之類,以滿足市鎮自主的要求。

香港的區,在上世紀六十年代至八十年代的satellite towns,如荃灣、沙田、屯門等,也是按照歐洲的區來主理,是自給自足的,八十年代之後,香港政府改變了區域行政政策,用mass transit鐵路運輸和MTR上蓋建築來加強人口的流動性,故此屯門醫院的醫生不必住在屯門,可以住在中環,中環上班的人可以住在屯門和元朗,用西鐵上班。整個香港的地理和人口佈置變得optimized(最優化),於是又繁榮起來,樓價也比較平均分佈,西鐵線、東鐵線、馬鞍山線、沙中線的樓盤也有人投資和保值,元朗「雞地」的爛地樓盤連結了西鐵也很值錢值租,撐起了香港的金融地產經濟。

現在,政府竟然之前有人說要搞小封區?我看他們根本未了解好香港的區域行政已經改變,不再是他們七十年代做民政主任期間的satellite township的時代,香港已經變成一整個Metropolitan community整個香港相當之mobile和vibrant,七、八百萬香港人加上大灣區人員在香港靈活調配工作和盡情吃喝購物消費,而不再是幾十個寧靜小區,以前屯門公路下雨塞車就遲到返工、在巴士上打瞌睡的good old days失去了,西鐵三十分鐘可以將你從屯門送到中環,你無遲到上班的理由。中環蘭桂坊餐廳的廚工在天水圍居住而不再是在西環的舊樓。土瓜灣、西環那些睡着了的社區現在也有地鐵站,樓價舖租升值。由於服務top efficient,消費能力top in the world,各種良好人才、物料和服務聚集香港。Life in HK becomes top expensive but we have the best quality of life here!

如果是封區,目前香港這個Metropolitan community已經封區了。不通關、不解封機場、全港食肆宵禁,香港不是封區了嗎?




政府的存在,不是為了道德的善,而是維持公平和中立的服務

香港官員走不懂得統治香港的,因為統治香港的知識在倫敦。曾蔭權講過,殖民地時代,他返工的第一件事,是接聽來自倫敦的「教車師傅」(英國長官)的指示。以前這些統治知識是英國殖民地部(1968年改稱外交及聯邦事務部FCDO)的官員和倫敦的學者給予的。我在葉國華先生的香港政策研究所做事的時候,專門請很多前殖民地高官和西人顧問給我開會講學,葉先生知道,這些知識如果流失,香港無法統治。

英國官僚在Yes,Prime Minister的電視片集(第28集 The Whisky Priest)(1986-1987),如此形容政府的職能:

"Government is not about morality. It is not about good and evil. Government is about order and chaos. It is about stability. Keep things going. Prevent anarchy. Stop society falling to bits. Still being here tomorrow."[10]

The Complete Yes Minister, Jonathan Lynn, Antony Jay, P. 454. Google books


中立不偏維持穩定狀態給所有公民,英國的政府是經營一個fair playing field and level playing ground,這是深刻的公共服務思想。
