Having read several threads on similar subjects recently it seems to me that learning to fly is like losing your virginity.
You've read the books, surfed the web, (ahem) maybe watched a video or two, been told what to do and it seems that 'everyone else' has done it/is doing it without any problems.
Now you're in the circuit (for which read out on the pull), all tense, fumbling around and it just doesn't happen. To make matters worse, you have a chaperone watching your every move from the right hand seat.
The answer is perseverance and practice. One day it all just clicks and you have the rest of your life to enjoy it.
Seriously though, unless you are a true Sky God four lessons in the circuit are a small fraction of the ones you're going to need. I'm sure we all felt the same at this stage.
Good luck
