Focusing on life happiness is too hard. That is the key to unhappiness.
How Can I Be As Unhappy As Possible?
James Altucher

True, focusing on life happiness sounds like thinking about whole life, but life is much shorter, life is now, life is today, as I grow older, I want to make my wife happy now, I want to walk my dog, I want to connect with my brother and sisters, and I want it today, for a while, all I cared about was business meetings, metrics, KPIs, long term development plans, consistent strategies, but now, I just want to kiss my wife and walk my dog. And my business meeting are even better now a days.
