I agree with part of that, bot also disagree with some other parts.
I hate those motivational quotes, but I believe all there is, is trying, is the effort it self. But what if I try for something that I can lose easily (like money) then there's no point in trying, but there are higher values that are worth trying for, that are not gained or lost easily. Hard to describe them using words, things like being reliable, responsible, aware. They all need constant effort, but they're worth it.

Though if one doesn't believe in some sort of existence after death, then all these become meaningless. Personally I'm still searching for things that will be with me, even after death.
