I agree with p4's. I know you're new to this forum. I have been playing for 4 years and I assume p4's has been playing for pretty long as well. Every day, a month after i started playing, I thought I was "good." The truth is that not until 3 years ago was I remotely decent (I played 200 nl) and not until about 4 months ago would i consider myself good. Try to keep a humble demeanor about yourself, always try to learn, and set some structure to your stakes played and BR management.

I'd probably go ahead and start playing $25 nl cash games.
