I thought it would be useful if I explained what a nerd was. What I came up with was: someone who doesn’t expend any effort on marketing himself.
A nerd, in other words, is someone who concentrates on substance. So what’s the connection between nerds and technology? Roughly that you can’t fool mother nature. In technical matters, you have to get the right answers.

Annus mirabilis is a Latin phrase meaning “wonderful year” or “year of wonders” (or “year of miracles”). It was used originally to refer to the year 1666, but is today also used to refer to different years with events of major importance such as 1905 when Albert Einstein published his breakthrough four articles on Physics.
1666 – Isaac Newton
In the year 1666, Isaac Newton made revolutionary inventions and discoveries in calculus, motion, optics and gravitation. As such, it has later been called Isaac Newton’s “Annus Mirabilis.” It is this year when Isaac Newton observed an apple falling from a tree, and hit upon gravitation (Newton’s apple). He was afforded the time to work on his theories due to the closure of Cambridge University by an outbreak of plague. Going to his country home, he thought about many things that, in Cambridge, he did not have the opportunity to do with such devotion.
1905 – Albert Einstein
The year 1905 has very much been linked to the term “annus mirabilis,” as Albert Einstein made important discoveries concerning the photoelectric effect, Brownian motion and the special theory of relativity. These articles were published in Annalen der Physik.

I think the solution is to work in the other direction. Instead of working back from a goal, work forward from promising situations. This is what most successful people actually do anyway.
In the graduation-speech approach, you decide where you want to be in twenty years, and then ask: what should I do now to get there? I propose instead that you don’t commit to anything in the future, but just look at the options available now, and choose those that will give you the most promising range of options afterward.
It’s not so important what you work on, so long as you’re not wasting your time. Work on things that interest you and increase your options, and worry later about which you’ll take.
Suppose you’re a college freshman deciding whether to major in math or economics. Well, math will give you more options: you can go into almost any field from math. If you major in math it will be easy to get into grad school in economics, but if you major in economics it will be hard to get into grad school in math.

Dreams feel real while we’re in them. It’s only when we wake up that we realize something was actually strange.

當我看這部電影時，不覺有不妥。但是，現在想起來，劇情有很多細節奇怪的地方。
這正正符合「Dreams feel real while we’re in them. It’s only when we wake up that we realize something was actually strange.」的意思。

通常，興趣方面，你可以選擇，只處理最喜歡的部分；
通常，工作方面，你不可以選擇，避開最煩人的細節。

所以，如果把「興趣」化成「工作」的話，它不會再是你是「興趣」，除非，你把「工作」再化成「興趣」。

蜘蛛俠格言：
能力越大，責任越大。
— 蜘蛛俠, Spider-Man, 又名「失敗的男」
.
As opposed to the Dilbert Principle, the Peter Principle assumes that people are promoted because they are competent, and that the tasks higher up in the hierarchy are more difficult to excel at. It concludes that due to this, a competent employee will eventually be promoted to, and remain at, a position at which he or she is incompetent.

當你相信「能力越大，責任越大」時，不知不覺間，你會變成一個「失敗的人」。
每當你變大了自己的能力時，就立刻加大自己的責任的話，
你在任何時間，都沒有額外的心神，提升生活和工作的質素。

Fields Medal (2006), declined
Millennium Prize (2010), declined
Sir John Ball, president of the International Mathematical Union, approached Perelman in Saint Petersburg in June 2006 to persuade him to accept the prize. After 10 hours of persuasion over two days, he gave up. Two weeks later, Perelman summed up the conversation as: “He proposed to me three alternatives: accept and come; accept and don’t come, and we will send you the medal later; third, I don’t accept the prize. From the very beginning, I told him I have chosen the third one… [the prize] was completely irrelevant for me. Everybody understood that if the proof is correct then no other recognition is needed.”
