Life is short. Take more chances.
Watch the talk
Life is short, take chances, collect experiences.
(A bajillion of effort) x (the chances you take) = ultimate life success, fortune, eternal happiness.
What you get is avoiding the state of would've-could've-should've, which to me is the biggest driving force I have everyday.
If you take chances - one of the things I've learned is that you've got to give chances! It does work like that. You have to take some and then give some.
