If you're asking for a short cut to becoming a better player then I'm afraid to say I don't there is one. The only way to get better at poker, like everything in life, is to keep plugging away constructively. Also, imo part of being a good player is patience. I've noticed that a lot of major leaks have always occurred about 3 or 4 hours into a session; when I'm a bit bored, not catching much and a bit impatient in general. These forums are a great place to start though. Although I'm a new recruit at the moment, I've been lurking here for ages and 2+2 even before that. It's definitely improved my game for sure. Stick around, follow good advice, put in the hours and you'll be in higher stakes no problem
