I have two (at least) racing bad habits that I struggle with constantly, and I'm interested in what demons other drivers battle. These are the things that cause you to say, "I can't believe I did that AGAIN!" For me, my two sins are turning in early and staying in my lane. I attribute the turning in too early to being ugly, fat, old and used up and my reflexes aren't anywhere near as good as they were decades ago. So I get anxious and turn in early. Blind corners are real trouble for me because of this. The "staying in my lane" thing is a result of driving on the street for nearly 50 years. I find that instead of "straightening out" a corner and using all of the track, I'll drive it as though it were a two-lane highway and you have to stay in the right lane (in civilized countries where we drive in the right lane).
