It helps a lot, when you write your mistakes and ideas during the skate-session down.
I read them everytime, before I go out. It helps a lot to improve much faster and break bad habbits.
example:
1. wait a few milli-secounds more before you go up again -> more concentration and more balance. this was one of my main mistakes. too hectically. now I stand tricks way more often.
2. "shoulders parallel to my board."
