I don't read anything excessively critical of the OP but I do wonder why he hasn't been pointed more clearly at the most obvious solution: more training. If he is a genuine poster and does have a PPL, there's nothing at all to stop him going along to a reputable training organization and asking for a few hours of remedial instruction. Most training organizations I know would be happy to help and, indeed, I've known several mature-minded people, in both recreational and general aviation, who've done exactly that. No shame at all in asking for a supplementary navex through controlled airspace, then following it up by having an instructor (or experienced pilot) sit in the right hand seat while you do some more.
