I'm sure that there are many players who actually can relate to what you've written here in one form or another.
I too have read every freak'n book, every article etc. that I can get may hands on but am actually addicted to that stuff... and like it.

I think (I mean "I know") my biggest leak in poker is in the Poker Mindset & psychology stuff..... ie. 'losing the ego' being a big part of that. It is for sure the area of my game that I find I need to work on the most at this stage of the game.

Good Luck on your path.
