Well, I am not setting the world on fire but I am profitable though only in the micros. It took about a year for things to click. Three things have helped me.
1. This forum. In particular OZExorcist made a post on building from a baby
bankroll that should be stickied by someone in power
https://www.cardschat.com/forum/learning-poker-57/building-baby-bankroll-181238/
Also, when it comes to cash games anything that WVHIllbilly or Stu Ungar post is gold. There are other great posters but that will certainly get you started.
2. Training videos. I personally use Deuces Cracked but Drag the Bar is heavily involved in this forum and they have some great coaches. You can't go wrong with either one. I found that videos really helped me see how to apply concepts that I had read about previously but had not been using correctly.
3. Dusty Schmidt's book "Treat your Poker Like a Business" was inspiring. It kicked me in the butt and I got focused on playing a lot and working on my game in a more structured manner.
Probably more than anyone wanted to know but I'm pretty fired up about improving my poker. Also,while it took me a year or so to start showing a profit. Most of that time was because I was not doing things properly. Once I started doing the things listed above my progress leaped forward and since the end of September I have been trending steadily upward.
