I went to a few trading firms. Most are male, looking like shit. Most are smoking, looking like out of their minds, with dirty cloth, messy hair. Personally, once I was in this trading/investing for full time, I became very unhealty -- unlimited data/10Q to read every day. Tough decisions every day. Those all left traces in my health. I am now less interactive with real people, gained weight, slept very little. Many of my friends say I don't look normal now. How do you keep yourself FIT, Normal in Society?
