Just tossing a different idea out there. Watch yourself!
There is software out there that will allow you to record your own poker sessions. Play and record a few and then go back and watch yourself. Ask your self if you made the right decision at the time. Play the hand from your opponents position and how they played against you and why.
Even if you won the hand, did you extract full value?
Even if you lost the hand, did you lose the minimum?
You would be surprised what you learn about yourself and how your opponents view you. You can use that against them later.
