Sometimes, you have done something you regret. You want to go to the past to undo what you have done. You cannot do so as you are already your-now-self. You cannot become your-past-self anymore. You cannot send a message to your-past-self.
Sometime in the future, your-future-self would have done something he regrets. He wants to go to his past to undo what he has done. He cannot do so as he is already his-now-self. He cannot become his-past-self anymore.
However, YOU can help him. His past-self is YOU. His past-self is your now-self. You can know what he has done wrong by receiving messages from him.
Live as if you were living for the second time and had acted as wrongly the first time as you are about to act now.
— Victor E. Frankl

Sending messages to your future-self is much easier.
Writing.
If you want to send a message to your ten-year-later-self, write it down. Put the message in a drawer. Do not read it until ten years later.
This is the meaning of writing.

Extend yourself
.
To meet your past and future self now, just extend you to other people, e.g. your brother, your grandpa …
The method is to extend yourself beyond your personal-self. When you see your younger brother, you may regard him as your past-self. When you see an old person, you may regard him as your future-self.
Learning from other people’s experience can emulate the effect of receiving messages from your future-self.

3.5 Time messenger
A time messenger is someone who can send and receive letters to and from the past and to and from the future.
You are a time messenger.
3.5.1 send messages to your past self
You cannot send messages into the past. Even if you can, you cannot receive it, for you have already become your now-self. Only your past-self can receive the message, your now-self cannot.
3.5.2 receive messages from your future self 接收來自未來的訊息
You can receive the message sent by your future self because you are your now-self now.
What if your future self did not send the message you want to receive?
That is nonsense. You are always creating your own future-self. Your future-self is under your control.
How to receive messages from your-future-self?
Vision: 先知先覺 洞悉先機
To receive messages from your future-self, you need vision.
Vision is a function of common sense. Common sense is a function of vast knowledge and creativity.
How to get such knowledge and creativity?
1. Read
2. Observe
3. Experience
4. Create
Then imagine yourself as your ten-year-later self. If you are yourself-in-ten-year-later, what would you want to tell your now-self?

3.4 Living in now-here, eliminate the passage of time
If you have always unleashed all the potential of time, you will not fear the passage of time. Since rather than being gone, time is transformed to something more valuable.
Just like when you have bought something that deserves much more than its cost, you would not feel that you have lost the money.

3.3 You are nowhere but nowhere
.
People always have an escape-character.
We often think that the past is better than now (good-old-days thinking); or the future will be better than now (procrastination).
Thinking in either way is not useful, for you are always here, you are always in now.
You are in nowhere but now-here.

3.2 Now is the past of the future, the future of the past
.
To get a feeling of traveling into the past, imagine you are a 22nd century person and enjoy the present technologies.
To get a feeling of traveling into the future, imagine you are a 19th century person and enjoy the present technologies.

Storyline 1 … to be a time traveler …
.
3.1 In the beginning, …
Time traveling means traveling through time to different eras in history.
To the best knowledge of the known physical laws, time traveling is not feasible.
I was really disappointed until I started to realize that …
.
3.1.1 in a sense, we are all time travellers
We are travelling into the future now.
If you want to preserve your coordinates, , in space, you can simply choose not to move. You can be static in space. You can choose not to change your position in space.
However, even if you want to preserve your time coordinate, , you cannot.
You are always moving from the past, through now, into the future.
The -coordinate in
always increases.

Pascal’s Pensees:
Words differently arranged have a different meaning,
and meanings differently arranged have different effects.
.
In an A.Maths lesson (2006): I said,
係理論上, 理論上同實際上係無乜分別o既;
但係實際上, 理論上同實際上係有好大分別o既.
(1)
The next day, in a G.Maths lesson, a student said she would collect my words to construct a quotation book.
As a joke, I said,
I am going to publish an autobiography.
Its name will be “我與A.Maths 爭鬥三十年“.
(2)

Footnotes:
(1) Written Chinese and English versions:
在理論上, 理論上和實際上是沒有什麼分別的;
但是在實際上, 理論上和實際上是有很大分別的.
The difference between theory and practice is small in theory but big in practice.
.
The original quotation is “The difference between theory and practice tends to be very small in theory, but in practice it is very large indeed.” — Anonymous
I discovered this quotation from the book Open Sources: Voices from the Open Source Revolution in 2002.

4. 專等於博
假設你的核心學問是物理.
物理是你知識網絡的中心.

第一層次的看法是 中心為專 周邊為博.
第二層次的看法是 以專攻博: 透過物理掌握其他學問.
第三層次的看法是 以博攻專: 透過各門學問掌握物理,
以物理作為, 各門學問的學習主題.
例如:
學數學時問, 這個物理課題, 需要哪門數學? 需要知到甚麼程度?
學語言時問, 物理文章恰當的風格是甚麼? 用甚麼字眼可以, 令行外人也能明白?
學心理時問, 研究物理需要, 甚麼心理素質? 物理大家的思考方法, 工作習慣中, 有哪些是值得學習的呢?
學程式時問, 這冗長的運算是必須的嗎? 可否用電腦來代勞?
.
第四層次的看法是 專博合一:

PHYSICS = logic + language + mathematics + physics + chemistry + computer + psychology + …

當一塊大鑽石弄碎時, 價值只等於許多小鑽石.
當一個偉大的心靈, 被干擾而分散時, 就只是一個平凡的心靈.
偉大心靈的優越之處在於, 集中一切心力於某一點, 如凹鏡集中所有光線一樣.

3.21 迷宮
走迷宮是不是勤力就可以趕快完成呢?
不可以.
.
走迷宮時, 只要選錯一條分叉路, 即可令你前功盡廢.
那走迷宮怎樣可以高速完成?
直昇機.
.
只有直昇機可以令你看到迷宮的脈絡.
只有看到脈絡才可以有效率地完成迷宮.
.
3.22 G. Maths by A. Maths
現實中的直昇機在哪裡?
深一點的學問.
.
會考時有兩科數學: G. Maths 和 A. Maths.
A. Maths 很深.
但是它的好處是令人覺得 G. Maths 很淺.
.
為什麼有這樣的效果?
因為 A. Maths 比 G. Maths 深了一層,
為你提供了一個脈絡去了解 G. Maths.
讀G. Maths 時多了很多上文下理.
(G. Maths = General Mathematics; A. Maths = Additional Mathematics)

3.1 幻想智力
副題: 如何用小智力做一些本來要有大智力才能做到的事情
3.11 洗衣機與電飯煲
一個洗衣機無論怎樣勤力, 都不能煮飯好過電飯煲.
同理,
一個電飯煲無論怎樣勤力, 都不能洗衣勝過洗衣機.
致勝之道
在於
洗衣機要知道自己是洗衣機,
專心於洗衣方面發展;
電飯煲要知道自己是電飯煲,
專心於煮飯方面發展.
3.12 鱷魚與長頸鹿
人生的遊戲何其多,
記住,
要選擇自己會贏的遊戲.
如果你是魚, 你要同人鬥游泳;
如果你是長頸鹿, 你要同人鬥高;
如果你是豹, 你要同人鬥快.
思考題: 怎樣可以知道自己是什麼動物呢?

有些電腦程式是市面上買不到的,
要聘請程式員度身訂造,
專為某個特別應用而寫新的程式.
同樣, 有此人腦程式是不容易由自己安裝的. 原因可以是
a. 市面上根本沒有適合自己腦子的程式;
b. 即使有, 自己也不知道哪裏找.
這時候, 你需要請人為你度身訂造程式.

情境者, 上文下理也.

漂亮的畫面,
精彩的特技,
悅耳的音樂.
偏偏沒有故事劇情,
哪這部電影還有意思嗎?
