I wish you all the best on your quest. It will take much hard work, learning, desire, and an ability to learn from the setbacks.
I play because I love the game. I've been playing for a very long time, and I do keep track of how I do, and I've made a profit over the years, but nothing to brag about. It does keep it interesting, though.
Now that I'm retired, I have even more time to play, and I'm making good use of it.
One thing I've REALLY noticed over the years? Players that enter $10.00 and up tournaments, play a hell of a lot differently, than the ones below that level...especially
freerolls.
I tend to keep my buy-ins at the $5.00 level. I feel much safer there.
Again, if you've really got the desire, and drive, I wish you all the best.
Maybe you can keep us updated on your progress.
