Well I hope Gertrude didn't mean to be rude, but it's a fair point: you are lucky to be able to learn to fly while still fairly young. That's not dig: good luck to you! So don't be disheartened if you can't afford all the flying you'd like. As others say, if you're determined and single minded, you'll find ways.
And I'm sure you'll avoid the hazard of some single-minded flyers: to be so narrow that one can get a bit, shall we say, uninteresting to normal mortals. My wife's favourite joke about pilots: How can you tell when you're half way through your first date with a pilot? He says: "Enough about me, let's talk about flying".
