Translation 2
.
6.4.0 Create = teach or write or both
6.4.1 Create: Teach
6.4.2 Create: Write
.
The basic theme is that whenever you cannot understand something, you should try to create that thing.
How to create?
Write. Write as if you are explaining the materials to someone else.
As physicist Gerar’td Hooft advised, when reading a physics textbook “… imagine how you would write those texts in a smarter way.”
Why is that you can understand a thing when you re-write your textbook?
It is because whenever you write, you have to translate the materials into your own language.
You are CREATING your OWN knowledge.

The Power of Myth 2
.
A few weeks later, the Great Depression began. Campbell would spend the next five years (1929-1934) trying to figure out what to do with his life (Larsen and Larsen, 2002:160) and he engaged in a period of intensive and rigorous independent study.
Campbell states that he “would divide the day into four four-hour periods, of which I would be reading in three of the four hour periods, and free one of them… I would get nine hours of sheer reading done a day. And this went on for five years straight.

6.3.1 Feynman’s Blackboard
.
Physics
= Relativity + Quantum Mechanics
= 相對論加量子力學
= 深深深

6.3.2 Quantum Mechanics | 量子力學
.
When physicist Feynman was a student,
there were two versions of Quantum Mechanics.
They described the same thing
but in different mathematical languages.
One version was Heisenberg’s Matrix Mechanics (矩陣力學) , using matrices. Another was Schrodinger’s Wave Mechanics (波動力學), using differential equations.
Feynman could understand neither of them.
So he spent 8 years to create
his own version of quantum mechancis
in order to understand quantum mechanics [1].
Feynman’s version of quantum mechanics is now called
Feynman path-intergral. (路徑積分)
After Feynman’s death, [2] people found that Feynman had written some words on the left-hand top corner of his blackboard:
.
“What I cannot create, I do not understand.”
不是由我自己想出來的東西, 我都不能理解.
.

Personality
Don’t try to change your personality
Millions of people are wasting huge amounts of time trying to change their personality to please their boss or their girlfriend or boyfriend.
Number one, you cannot change your personality. All you will accomplish is turning yourself into a phony. Secondly, and more important, you don’t have to change your personality. What you do have to change, if your personality clashes, is your boss or your career or your girlfriend or boyfriend.

心理學家

We can discover this meaning in life in three different ways:
(1) by creating a work or doing a deed;
(2) by experiencing a something or encountering someone; and
(3) by the attitude we take toward unavoidable suffering.
.
.
It did not really matter what we expected from life, but rather what life expected from us. We needed to stop asking about the meaning of life, and instead to think of ourselves as those who were being questioned by life—daily and hourly. Our answer must consist, not in talk and meditation, but in right action and in right conduct. Life ultimately means taking the responsibility to find the right answer to its problems and to fulfill the tasks which it constantly sets for each individual.
