One of the draws to flying is that you are constantly learning if you are a 45hr PPL or 10 000 CPL, IR , ME, MCC, FI and any other rating under the sun!
The thing with me is that I'm very thorough, so I tend to think about and question things that most perhaps wouldn't. So because of this I always think I need to be a really really fantastic pilot before I'm allowed a PPL, but because learning continues even after getting the license perhaps I shouldn't worry so much. I'm sure that anyone with a PPL considers themselves a better pilot than they were the day they passed the skills test, just because of more experience. In the same way that my flying is much better now than it was on the day of my first solo.
