I try to spend all of my time with family and kids. I should focus on living and enjoying my everyday life and and don't pay too much attention to the market. However, the overall economic and market can still drag my mind out of my daily activities. Perhaps, a good investor is always someone like a Zen master.
There is an old Chinese saying: 无欲则刚, meaning you become tough when you no longer have earthy desire. It may be a paradox for investors because investors have inherent earthy desires: maximizing their returns :-)
