<prompt> Human: I asked this over on rflying, and thought maybe it would be better to run it past rpersonalfinance as well.Im 24, no debt, no bills, with a steady income. I have about 40k saved up. I getting to a point where Im beginning to think about house downpayments and marriage, but Ive also been struck with a love of flying and after an intro lesson Im hooked. Im going for the license now, but theres only one problem: its a lot of money. Around 10k for a years worth of lessons and a good for life license for single engine aircraft.Theres really no way to make it viable unless I get more endorsements on my license, but I dont plan on making a living off it anyway. Its purely for fun, and while I cant picture using my license frequently, it would be cool to have.So, how do you guys rationalize the crazy expenses for recreation and hobbies?  <response>: A good place to start is with this question Ive seen online:If someone put 10,000 in cash in your hands and said You can keep this money if you dont learn how to fly. would you keep the money or give it back?
