I bought the entire King Schools DVD training series and a couple of Sport's sets. Also bought a dozen or so books recommended to wannabes and also Flight Simulator with cyclic, collective and pedals for familiarisation in the cockpit, watching the effects of control input on the instrument panel etc. (Whether this helps or hinders in actual flight - I'll let you know!)
I've also got all the test questions, right through to CFII for constant review and pass the PPL written exams consistently - although I'm aiming for 100%. The aim being to have a good overview before I start.
I find that the older I get, the less I know, so age needn't be a hindrance to learning...
