No need to think so far ahead, take the 1st few steps. No matter, things could change some looking out a few years.
As those ‘1st steps’, look locally for some faster-track flight training. Just completing your Private would be a great start. If it never progressed beyond that & casual renting, you’re still a WINNER. Come on up to Oshkosh in July sometime.
There are aviation freebies you could start with today, the ‘Flight Training Handbook’ from the FAA website is a great download to start with, there are others.
A guy I know is taking lessons towards a Private in his mid 70’s. He said he may never even take a check ride, just at least wanted lessons.
You will learn so much in the quest for the Private. There are doors out there you can’t even see right now. No sense talking ATP now.
