My lessons (as distinct from strategy) I will share and are spread over several sentences:
- don't pick up pennies in front of the steamroller - for me I wouldn't pick up 1 tick moves or scalp and then let my loss be open ended and my position drift off into a massive loss because I didn't get that one tick, quickly hack off your arm before your entire body is crushed
- accept losses (even the occasional big loss and don't try to win it back, just go back to doing what works and put the loss down to a learning exercise)
- keep records of days, carnivals, individual races from year to year and go back over those records when you approach the same day, carnival, race the next year
- write down what you learn and go back and re-write those notes
