6. Maintain at least 3 close relationship
No matter how successful you are, it means nothing if you have nobody to share it with. So you are a millionaire, at the end of the day you still come home to an empty bed. Isn’t being lonely the worst form of misery? So no matter how bad or good your life is, make sure you maintain at least 3 close relationships. It can be with your parents, siblings, best friends or your own wife and kids. Looking at them, sharing memories with them will bring you happiness.
