Linux is headache. It gives you too many choices.
But Linux is necessary.

Applicants must also have extensive knowledge of Unix, although they should have sufficiently good programming taste to not consider this an achievement.

Many people do not like beauty.
Many people do not like to be intelligent.
Intelligence implies responsibilities. That’s why most people resist intelligence.

Imagine you were asked to invent something new. It could be whatever you want, made from anything you choose, in any shape or size. That kind of creative freedom sounds so liberating, doesn’t it? Or … does it?
If you’re like most people you’d probably be paralyzed by this task. Why?
Brandon Rodriguez explains how creative constraints actually help drive discovery and innovation.
With each invention, the engineers demonstrated an essential habit of scientific thinking – that solutions must recognize the limitations of current technology in order to advance it.
Understanding constraints guides scientific progress, and what’s true in science is also true in many other fields.
Constraints aren’t the boundaries of creativity, but the foundation of it.

We cannot change anything until we accept it. Condemnation does not liberate, it oppresses.

When faced with a decision, I always ask, “What would be the most fun?”

Do not be too timid and squeamish about your actions. All life is an experiment. The more experiments you make the better.
One experience [almost] always helps another, because the first experience betters you, to deal with the second experience; even if the first experience is unpleasant.

Information is the decreaser of uncertainties.
Actions are great devices to decrease uncertainties, for they gather feedback.

Action can decrease your uncertainty. That’s why the policy of “go as far as you can see, and when you get there, you’ll see farther” works, as long as the overall direction is correct.

“Choice” is the opposite of “direction”.
less choices ~ clearer direction
more choices ~ less clear direction

If there are no choices, there are no alternatives.
Thus, there is no opportunity cost to consider.
So sometimes, “no choice” can induce happiness.

Being a nice guy can be a problem, because “always being nice” gives no feedback and no directions. In effect, “always being nice” gives people an infinite number of choices. Remember,
choices ~ headaches
In other words, you should be nice as often as possible, but not always. Be angry when you have to.

Fear accompanies the possibility of death. Calm shepherds its certainty.

In my second time teaching (2007-2008), the magic disappeared because the unknowns had disappeared.
To get magic, you have to jump into the unknowns/future.

Throw your soldiers into positions whence there is no escape, and they will prefer death to flight. If they will face death, there is nothing they may not achieve. Officers and men alike will put forth their uttermost strength.
Soldiers when in desperate straits lose the sense of fear. If there is no place of refuge, they will stand firm. If they are in hostile country, they will show a stubborn front. If there is no help for it, they will fight hard.
— The Art of War (Sun)/Section XI
When there is no choice, there is no uncertainty.
You do not have to use any brainpower to make any decisions.
So you take the actions directly.
choice ~ uncertainty
fear ~ the feeling of uncertainty
no choice ~ no fear
別無選擇 ~ 沒有不安

Deadlines decrease the number of choices, thus decrease uncertainty.
Without a deadline, your brain will have so much uncertainty that it does not work at all.

Give me a million dollars and I’ll figure out what to do. But it’s harder than it looks. Constraints give your life shape. Remove them and most people have no idea what to do: look at what happens to those who win lotteries or inherit money.

Constraints decrease the number of choices, thus decrease uncertainty. Therefore, constraints give shape to your life.

這段改編自 2010 年 6 月 15 日的對話。
那你又不應太緊張。不安是因為不知道自己將會考成怎樣。但是，如果你跟足我提議的，「計時間計分數」做 past paper（歷屆試題）的系統，你就會在考試前，事先知道自己，會奪得大概多少分數。那樣，你的心情自然會穩定得多。
例如，如果考試前所做的那幾份 past papers，每道長題目的 d 部分，通常也完成不到，你就可以預計到，一分面，你不會奪得最高等級的成績；另一方面，你亦不會奪得太差等級的成績，因為除了長題目的最尾一部分外，其他題目部分你都可應付自如。
