Result-oriented

Posted on by

Another thing to consider is your definition of results. It’s possible that you could do every right … but still your business fail, …

There are some things that simply not in your control, and there are times when you have to define “results” in a different way than you might have thought:

Yes, my business is going through a rough time. But what am I discovering? What strengths am I gaining? What increased capacity will I have to apply to future efforts?

…

Even when the observable results appear to be negative, you can still make huge progress …

Enjoy everything, need nothing, 2.2

種子論起點 12.3 | 兩次測驗 2

有心栽花花不香，無心插柳柳成蔭。當你「需要」一樣東西時，你就會失去它。

又例如，當你「需要」得到好成績時，你就會失去它：你的成績即使不太差，亦一定不會是最好。

如果你「需要」有好成績，才會感到有自信的話，每次在學業上遇到挫折時，你都會覺得那是對 自身人格 和 自我價值 的一個否定。那樣，溫習時，你會戰戰兢兢，自然不能得心應手；考試時，你會惶惶不安，自然不可揮灑自如。沒有豁達的心靈，就沒有靈活的頭腦。你一定不會是一個一流的學生。

正確的心態是，謀事在人，成事在天。你要知道，沒有人可以控制到，究竟自己拿不拿到好成績，因為影響成績的因素，實在有不少。你唯一可以做，唯一可以「控制」的，就是運用最好的策略，把試前十分有限的溫習時間，發揮至最大的功效，盡量提高「拿到好成績」的機會率。

在考試臨場作答時，你要使用同樣的心理結構。你可以控制的，是盡力作答，拿得一分得一分，從而提高「成功」的機會率。至於最終成不成功，或者最終拿到多少分，則完全不在你的控制範圍以內。

Logical arrow of time, 2

Posted on by

However, the right definition of the past and the future is independent of these sign conventions for spacetime coordinates. The right definition says that

    The future is evolving from the past (and the present).

Correspondingly, the calculations that are designed to theoretically mimic this evolution have the same arrow:

    The future is calculated from the past (and the present) as long as we use the usual calculations that resemble the evolution.

It’s important that you can’t exchange the words “future” and “past” in the sentence above.

That doesn’t mean that science can never say anything about the past, by manipulating with the present data or the data from a closer past. But this type of calculation is different from predictions of the future. It follows different formulae, too. They’re the formulae of logical inference, e.g. Bayesian inference.

And as we have explained many times, the results of this inference – the retrodictions – always depend on our priors. So the knowledge of the present is enough to calculate the future (classically) or to predict the unique probabilities of various states in the future (quantum mechanically). But it is simply never enough to calculate the unique state or unique probabilities of various states in the past.
