如果只有我一個人，在茫茫宇宙間，像荒野中的一條狼，生於孤獨，死於孤獨，無人思念，也沒有牽掛，那麼，我就不會憂傷。
我憂傷，是因為擔心你會憂傷。
如果你也抱有我的思想和信仰，我就不會憂傷。

Hacker: Prequel
4.10 Hacker approach [10]
.
1. “a belief that even though you may not know all of what you need to solve a problem, if you tackle just a piece of it and learn from that, you’ll learn enough to solve the next piece – and so on, until you’re done.”
–Eric S. Raymond’s How To Become A Hacker

1.5 “a belief that
even though you may not know all of what you need to solve a problem,
if you tackle just a piece of it and

you’ll learn enough
to solve the next piece
– and so on,
until you’re done.”

時間長度
.
一剎那者為一念，二十念為一瞬，二十瞬為一彈指，二十彈指為一羅預，二十羅預為一須臾，一日一夜有三十須臾。
— 佛教梵典《僧只律》
.
.
推算:
86400秒＝一晝夜＝30須臾＝600羅預
＝12000彈指＝240000瞬間＝4800000剎那
.
.
換算成秒數：
一「須臾」＝2880秒（48分鐘）
一「彈指」＝7.2秒
一「瞬間」＝0.36秒
一「剎那」＝一「念」之間＝0.018秒

花千樹
東風夜放花千樹，更吹落，星如雨。
寶馬雕車香滿路。鳳簫聲動，玉壺光轉，一夜魚龍舞。
蛾兒雪柳黃金縷，笑語盈盈暗香去。
眾裏尋他千百度，驀然回首，那人卻在，燈火闌珊處。

“The accident left him without hands and mostly deaf and blind when he was 19.”
“Heim had to undergo a series of operations after the explosion which resulted in the loss of his arms. He found that intense concentration on the study of Einstein’s relativity theory helped him control the pain in his arms mentally and physically.”

4.8 Follow your bliss
.
BILL MOYERS: Do you ever have the sense of… being helped by hidden hands?
.
JOSEPH CAMPBELL: All the time. It is miraculous. I even have a superstition that has grown on me as a result of invisible hands coming all the time – namely, that if you do follow your bliss you put yourself on a kind of track that has been there all the while, waiting for you, and the life that you ought to be living is the one you are living. When you can see that, you begin to meet people who are in your field of bliss, and they open doors to you. I say, follow your bliss and don’t be afraid, and doors will open where you didn’t know they were going to be.
* * *
My general formula for my students is “Follow your bliss.” Find where it is, and don’t be afraid to follow it.
– Joseph Campbell, The Power of Myth, pp. 120, 149

“There’s a common misconception that a person’s skill is their talent. Skills, however, are not talents. Talents, on the other hand, requires skills.”
— The 8th Habit p.76
.
“Don’t confuse transferable skills with traits.”
— What color is your parachute? 2005 Edition p.141
.
.
大部分人也分不清技能與天份.
天份需要技能的支撐. 但是技能本身不是天份.
.
例如:
如果你的運算能力技巧很差的話,
你很難說服人你有數學天份.
.
但是即使你的運算能力高,
亦不代表你有數學天份, 有數學傾向.
因為除了運算能力外,
數學天份還需要其他技能和性格特質的支持, 才能發揮.

找例外 5
4.5.2 part 2
“Do not follow the rules. Instead, look for exceptions.”
– What color is your parachute? 2005 Edition
.
.
不要老是跟著規則走.
老是跟著規則走的話, 你會損失很多 大機會.
.
.
例子二:
以前在實驗室工作時,
教授請來了一位同事.
該位同事的寫程式才能很高.
.
.
但是研究院認為他的英文能力未達基本要求, 不能收他.
另一方面, 教授卻認為該位同事是一位程式奇才, 不能放棄.
結果, 在教授的推薦下, 研究院收了他.
條件只是要他補考英文的公開試, 以證明他的英文有進步, 已達研究院的英文基本要求.
.
.
試想想,
如果那位同事是跟著規則走, 按一般程序報讀研究院的話,
以他的英文能力, 在第一階段的遴選將會被拒絕.
.
.
哪他怎樣不跟規則走呢?
.
.
他先找教授, 說服教授
他的程式能力是一個大優點.
這個優點所帶來的好處, 遠遠超過他的英文所帶來的不好處.
而他英文差這個缺點是不難補救的.
令教授願意收他為研究生.

生物時間論
( 改篇自BBC紀錄片<<Supersenses>> )

人的年紀越大, 身體的新陳代謝率會降低, 而心跳也會減慢.
自己內在的生理時鐘越慢,
相對來說, 外在事件的節奏就會顯得越快.
