Play big or don't play at all? I need help

[D.J.]

I'm not sure how to put this or what exactly I am asking but here is my issue. If I am not playing in a fairly big game like a 20-40 blind, 50-100 blind or maybe a deep 10-20, I don't think that I play very well. I don't know if it is the fact that I am playing against better players, the amount of money on the table, or maybe even fear, yes fear that I have playing in bigger games that forces me to play my best. I know that I make much better decisions when stacks are deeper and the money is greater and I also think I make much better reads against the players in these games as well. I guess my question is does anyone else feel this way? Is this a common problem? or what is the explanation for me feeling this way?
