'When / how do we know it's enough?' Listener question

1) Looking at the world scale problems I often see greed as the main driver which causes the problems. Some days ago after reading your book Sane I got an insight that greed is only a symptom of our phantom self which is perceived separate, lacking, not enough etc. The end of this madness will come only by realisation- lifting awareness of who we truly are, a space where life arises and that the self which is being defended, secured is only a mirage in the desert. 

2) I have a question for your podcast :) Looking at self improvement field in my eyes look as tool to get in this endless search to be better, to get better, to feel better. But more as I look at it I see this phenomena produces more problems than solutions. It takes us to this neverending journey where goal or peak of the mountain is even not seen and defined. So I wonder when/how do we know when is enough?
