What is the Aim of Life?

Maybe it is simple: to be good.  But if that is the aim, why is it so?  What is the compelling reason to be good?  

This question of compelling reasons raises another question.  Can we be good without compulsion?  We can try but why put ourselves out if there is no reason to?

Very simply I say that there has to be a reason, and all creatures needs compulsion to be good;  and thus incentives matter.
