Don't be negative about your talents.
I was 32 when as a motorcycle rider & working far away from home I first decided to have a go at flying,
Then had to break the learning sequence between Sydney Aus. and U.K. Shoreham Sussex - it took some 15 months (lowish finances) and just under 40 hrs to GFT.
Heard about the PFA - now LAA - and shared ownership initially got me into the fun side of light a/c ownership; I have stayed PPL ever since,
Radio licence wasn't necessary or done legally till much later.
As for Nav. well with the magic of GPS & mapped screens nowadays it should be easier really !
