I wanted to fly when I was 16 and pennyless.
It took me until I was 40 to finally realise my dream and looking back I know for certain that if I'd committed myself I'd have been a profesional pilot instead of a mechanic.
Alright so now I own a moderately successful business that can just about support aviation as a hobby, but oh how things could have been different if I hadn't been so slow to realise that in order to succeed in life you MUST stick your neck out, and the sooner you do it the better.
Once you decide on a goal you can then decide on the path to get you there.
