There are a number of interesting books out there about experience versus accidents. Fate is the hunter and the killing zone are two great ones that comes to mind. it is true that when you are very low hours you are afraid and have a healthy respect. As your experience grows you get a bit more blaze and as it grows more and assuming you survive the blaze stage you realise you are always learning. I am coming up on 3000hrs and still look at every flight in wonder and with a very healthy dose of respect thrown in.
Don't obsess on it, just go out and enjoy your self and be careful!
