Point noted, with kindness and sincere attention. But do please allow me a counterpoint....
Some us have dearly nurtured goals. In your case, it was learning to fly an airplane. In my case, when I try something merely for pleasure, entertainment or idle curiosity, I get bored or frustrated. To your example of flying... I'm an aeronautical engineer. Love airplanes in general, and thought about flying... but am terrified of heights, don't like to follow directions, and in general am a sloppy person. Probably not an idea combo for flying, right?
Over the years I realized that I just really want to have a lot of money. Not to spend it, not to show off, not to enjoy it, not even to wield power with it as some nefarious backstage manipulator. No, I just want to have it, to feel it, to indulge in the sensation of beholding it... and to watch it grow... even if that means living in a cardboard box, or more appropriately to my screen name, in a cracked jar.
If I die in 5 minutes, that's OK (will revisit this thread to confirm...). If I die prematurely that's also OK. What's not OK is a long and tumultuous life, witnessing my money decline, or at least, to fail to grow. That feels like a failure and a betrayal of core principles. I don't look back to 30 years ago, wondering why I didn't take such and such a trip, or buy such and such a thing. I do look back, to the extent that memory remains accurate, and upbraid myself for indulging in such-and-such. Better to have lived a more thrifty, ascetic life. I also regret having missed "obvious" investment opportunities, which are the flip-side of regretting spending.
My goal has been FIRE for decades, but mainly as a giant middle finger to The Man. I hate following directions, getting up in the morning, dealing with requirements or deadlines or constraints. Work, in a word, sucks! But so does not receiving a paycheck. I've not been able to square that circle. But here's a circle that most definitely I CAN square: I'd much rather die "too soon", than "too late".
