Rewarding careers

What is your career? My last child is almost in school and im ready to go back to school or the work force once the time comes! Ive been a sahm since i was 18 and went to culinary school for a little. I love cooking and still want to be a chef but at the same time i want something more rewarding. I love physical activity if it makes a difference. So many ideas are coming to my head like a at home catering business (making special meals at home and selling them to go. Ill also include nutritional values), personal trainer, firefighter, chef, heck ive even thought about being a fitness model but i want to know what other careers there are that most people dont think of.
