Welp, I had considered gigolo, piano player in a bar, dog trainer or dance instructor. lol I really don't have too many other talents. But in truth, I saved money and had a good financial advisor, I invested well (most of the time-knock on wood), always bought used cars with low mileage, bought a little property, liquidated some things, I stayed out of debt, and I bought a crap ton of insurance. Multiple policies. Diversify your investments also.
You need a real financial plan for your future and you cannot start one too early in life. Find something you love that you would enjoy doing just as much as flying. Even if it doesn't necessarily pay as well. Live within your means. You really don't need as much crap as you think, to be comfortable and happy. Marry the right woman or man...... I can't stress that enough.
Maybe work a part-time gig- again of something you like, which is flexible, maybe unique and save that money and gain some experience doing something else. You never know what you can expand or the contacts you will meet or how the pieces of the puzzle may fall together. And if all else fails think of a small business (again-something you would be interested in and enjoy) that you can start if the crap does hit the fan, that won't take a lot of capital to launch off the dock.
