I think many would disagree with me. But damn, why make shit harder on yourself. If you weren't staked, I wouldn't say what I am about to. But, with a stake your goal is to win money.

Who cares if you understand merging and balance at 4nl? Play a style that will yield profits. Learn when you have to. Make poker accretive.

Get a base of 13/11 or whatever the current style is. Then add one concept at time and only 1. Master it. Then move on. If you are .5ptbb/100 winner at 25, with a very unimaginative game, if you add just one simple concept you can increase your winrate, while still earning monies.

Also, it looks like you don't even like poker and get bored easily. You like the theory of poker, but the practice is boring, and who doesn't love some grade A mental masturbation?
