When I am no longer feel schadenfraude to people or thing. Neither do I feel unnecessarily proud of my position or belongings or achievements. When I have enough for my needs, and I am not in greed to get what I want. When I am satisfied enough. And whenever I am not, I capable to let it go. For I couldnt change the world or everything in it.
When I feel nothing with what I do and appreciate more what I have. When I less worried. I think by that time I am happy.
p/s: I think, I sound like a hippie
