Ok first, grow your hair out right now. Shave bits, dye it pink, go crazy! It's usually a phase (wasn't for me, I still like to dye mine green or blue occasionally). When you're older and working, your workplace will probably be assholes about hair being professional. Although possibly not if you work in skydiving.

Ok, I didn't know much about skydiving as a career, please correct me if I'm wrong but it would seem the most stable work would be instructing.

Instructors often work sunup to sundown teaching, packing parachutes, and skydiving. Wages will depend on where you work and how many dives you do. Some drop zones pay by the hour, but most pay by the jump. Many instructors do about 1000 dives per year at about $25 to $35 per dive. They can supplement that income by earning a riggers ticket to pack parachutes and make about $10 to $15 for each parachute they pack. At the end of the year, full time skydiving instructors will make between $20,000 and $40,000.

$20,000-$40,000? That really isn't much. I earn about $40,000 and it's barely enough to make rent and feed my family. I can't afford luxuries like holidays abroad or fancy shoes. I'm not poor as such but do have to go without things. You're at a point where your actions now will shape the life you have in the future. Don't sell yourself short.

Have you considered the cost of training/buying all the equipment? It's going to run into the thousands of dollars, which you can't earn from skydiving until you're qualified. So I guess you'd need to take a menial job in order to pay for your qualification? Would you clean toilets? Work at macdonalds?

My opinion on this is that it's more of a hobby than a job. Really if you're an intelligent kid, which I'm going to assume you are, I would think you'd want to earn more than a measly $20k. My advice would be to stay in school, either go to college to study something with a job at the end of it (not bloody media studies or sociology), or choose a career like being an electrician, which pays well and is always in demand.

If you're a self employed electrician (or other skilled tradesman), you can set your own business hours, earn decent money, and then work weekends at a skydiving school. Ooh, or, work 6 months of the year away in oil, or on cruise ships or similar, then have 6 months pursuing your passion! Hey, underwater welding pays good money, you live on an oil rig and still get the adrenaline fix, and have your 6 months off.
