Don't take any notice of the above two guys. Go with what you enjoy. I was in a well paid job for years but was miserable. Against all advice I got my licenses, flew TPs, got into debt but had a great time doing so! I'm now flying something bigger and am still happy.
Think forward by forty years. Wouldn't you wish you'd even tried to become a pilot? Problem is you are over seventy and it's too late!
Better to have tried and failed than never to have tried at all. Go for it!!!
