the only thing that i can add, is to watch out for the personal issues that can crop up. about two months after i went full-time, my wife and i hit the skids. nothing to do with trading, just personal issues. but this isn't about that failure.
its about the time and energy that it took away from my trading. i would have been much better off, if i had slowed my trading down. i could afford to not trade for a short time. at least long enough to straighten out my personal life. but didn't.
and to say the least it was almost a trading melt-down. and the last lesson i had to learn the hard way.
that being said. just watch out for the personal stuff and have a plan for how you are going to handle them when they do come around.
the only other nugget that i have found useful is to do something i like when the losses hit. it just seems to ease the pain, when i do something on those pesky losing days.
take in a movie. go hit some balls at the range, or maybe play a round of 9 holes. play ball with the kids, ride the bike, anything to take my mind off the markets. even if it is just for a little while...
good luck.....
