Buy a small plane and fly for fun. When you are older you can return to professional aviation after the bills are paid.
Or just fly for a living and pay the bills. Let someone else pay you to fly, rather than paying for it yourself.
Personally I'm not satisfied without flying; I do flying and non-flying jobs. I really can't see working hard for a living, however, only to spend that money on expensive aircraft rental or ownership, when I could be working for a living by getting paid to fly.
