i like to share my experiences... i still have some bad habits, like being very overweight in one stock, but that's where the stop sells come in... although if a stock were to gap down big i would lose big...
as for always taking profits... that is a very good habit to get yourself in... there are NO pie in the sky stocks... they all come back down and you don't want to be selling on the way down... imo it's much nicer selling on the way up!;)
