Ok, I'm still at the micros, but I decided to dabble in a higher limit. I normally play $25 NL and do fairly well and decided to try $50 NL. I can afford this limit, but my problem is the mentality for me moving up. I become very passive and overall intimidated. I've noticed most players play much stronger than at the 25 tables. Does this mean I'm not ready for the move? I feel I am laying down things that I wouldn't normally lay down. Should I keep grinding away at the lower stakes tables? Any advice on getting my head into the higher limits?

Thanks!
