Samantha has an interesting post. It reminds me of Gilda Radner:

*“Some stories don’t have a clear beginning, middle, and end. Life is about not knowing, having to change, taking the moment and making the best of it, without knowing what’s going to happen next. Delicious Ambiguity.”*

Gilda must be thinking about the relative importance of human actions and sheer luck in life. She argues that we cannot completely control our future, but we can partially influence it by taking proper action now.

Now let’s try to make her idea more precise.

In current period , I have a reward of happiness. is the action I take in period , is a random element that summarize the external, environmental impact on me, say luck; follows probability distribution , where is the history of actions I’ve taken and external factors till now. Hence, the future may not be completely chaos: although I cannot know future precisely, by taking actions now, I can influence how future will unfold via .

Suppose I am a rational hedonist, in a disciplined pursuit of happiness. In the current moment , I take the best action to maximize the expected, accumulative happiness from current time till the end of my life (a random variable), given the history . Let be the best accumulative happiness in expectation from now onward.

In this model, luck is captured by random variable . My karma will influence how future state plays out by partially controlling , which is influenced by relative important of action and luck . Given current history , I make the best decision , without knowing precisely (although I may know the distribution ):

.

That is,

*“taking the moment and making the best of it, without knowing what’s going to happen next.”*

Solving this model requires backward induction. The irony is:

*“Life can only be understood backwards; but it must be lived forward.”*

My brains shut down the moment I see formulas… I think I’ll stick to philosophies, haha. Thanks for linking me :)

Please bear with me: this week I am in the mood of revising my paper. So I have to live in that zone :)

I like how you used the probability functions to explain this. I would never have thought of applying maths or even relating it to such a thing. Its an amazing idea!

Thanks! It’s a bit stretched. Just for fun :)
