stop checking the turn when you have nothing, bluff off on multiple streets.
Stop always c-betting.
Learn to check-raise with
1. TP that figures to be good.
2. A monster hand
3. Pure air.

Then find out how much more action you get on AA from one pair hands and how often people will check the turn behind if they know you are capable of checking the flop with something and leading the turn or check.raising the turn.

In short, stop just bet/bet/betting every street when you have something and bet/checking-folding when you have nothing.
