2 leaks i have found so far

one is a long standing problem where i never fold when i get raised. this, i know, is a hallmark of a the fish.
two, when i don't know what to do in a hand, i often just click call. need to beat this one out of me.
3, i hate losing to fish and it drives me crazy when i keep losing over and over to people playing 75% of hands and more.
4, my attempts to do basic mental arithmetic are flawed through laziness more than a lack of ability.
