Well, I find that my trading sets my mood overall. If i am having a bad run, then you can bet I stick my head in the sand alot and avoid contact with other people. In my domestic life, this is easier to get away with since I am single, and trading defines much of myself. After 10 years it has gotten easier. I have seen alot and know what to expect. It is hard to keep your emotions in check with other emotional experiences. Especially being a daytrader because your mood will be altered every day! Just don't let the lowest lows outweigh your highest highs, emotionally.
My brother traded with me (us) for a little while and it was harder for him to put the wraps on it. He is married with 2 kids and the kids need a father, whether or not he made or lost money. The first question walking in the door from his wife was always about the $$, so that never helped things. He was very emotional and wore it continually outside of work. Ultimatley he ended up leaving. It still consumes him, but the heat was on from the beginning. Moved to Chicago with a wife / kid and started cold turkey. Went for his dream.
With the markets being a dominant issue for all, it is difficult to NOT discuss it. Every damn day I get a question about the markets. Especially the, "....where do you think it's going. / What stocks are good (I trade 80% 10 year futures)? I have given up the bullshit and just tell people my positions or that I have no f*cking clue. Especially with guys from work, the converstaion rarely turns from things other than trading related.
Wouldn't want it any other way, baby! During these turbulent times I think back to the days of parking cars and selling shoes. No thanks.
