Position size. Oversizing has lost me more than it gained, there were a few big banger moments, but bigger big loser moments not having the right position size. 2nd place, setting a stop loss, 3rd place getting greedy and not taking profits. Iv'e had positions up 1000% and I reflect back why I didn't take 90% off and leave 10% or 50% off. Now I don't make that mistake. I still oversize sometimes but with a stop loss and known risks and awareness its not so bad. So ya, those are my big thoughts. My #1 discipline now is ALWAYS TAKE PROFITS. If I lose 2k in a day on something, I often take 2k from somewhere else that's profitable, that way everyday I win, and it grows slowly but quickly.

Thank you! I'm just getting started, I've got more I'm owrking on, I'm new at this tech online stuff but I love it haha.
