I've welded most of my life, I'm 51 now. I'd suggest you start small and just do it as a hobby and build up to doing it for a living. Maybe try the wrought iron gate, burgular bar and fence market, that gives you a practical product to sell and still allows for artistic expression, you're not just spitting them out all the time. Burn out can happen with any craft, I suppose. I finally went to vocational school for welding after doing it by just coping what I saw--I really wanted to know why I was doing it a certain way, and that's important when welding different materials together. Go to craft shows and look at other types of metal working besides welding. I saw some cool stuff by these guys that coil copper wire together to make a lot of things, but would you want to do it eight hours a day, every day?? Most of all, find something you are passionate about. You're relatively young so you'll be around for quite a while doing it!! Good Luck P. S. It takes good eyes to be a good welder, If you have trouble with your eyes, that might become a concern.
