You're looking at it from the wrong way. You must look for reasons to FOLD.

Let's say you make a good bet with a pair. if he raises you there's already a big reason to fold since 1pair normally sucks.

But you probably go oooo and aaaa and boom, there goes your money.

This works for the other way around as well. If you got a big hand you probably bet too much out of proportion and give the opponent an easy reason to fold --> leading to you not winning big pots with nuts.

just my opinion. i go through the same thing.
