Evaluating happiness

I've had this idea for a while now. Let t be time you've lived so far, and Happiness(t) be a function of how happy you are at any given moment t. Then how good you've lived your life will be measured as an integral of the happiness function. If this evaluated over your lifetime is greater than 0, then your life was worth it, less than 0, not so much. Thoughts on my philosophy?

>user unironically mentions happiness
>mfw

cont'd
this thread needs more schopenhauer memes
good gracious, I have plenty

okay, well, first of all you don't define happiness, so this thread might as well go to trash, but for some unknown reason I would like to have you explain yourself
so... go on

But you've just shifted the problem, now instead of agonising over how to decide if you've lived a good life, you'll agonise over how to define the happiness function.

Congratulations, you've discovered microeconomics.

>Look at me, I just finished Calc 1. Am I smart now?

I'm retarded but not so retarded that I'd try to impress someone with calc 1 lol

Zamyatin did a sort of thing like this in his book. Was a bit contrived.
