Consider becoming a tradesman or artisan of some kind. General construction labor doesn't pay all that well, and is pretty boring, but if you have the skills, specialty craftsmanship can be very lucrative and fun.

You can make physical things you can be proud of, and you don't have to use a computer. Also, at some level, it is "design" work, because even if you don't draw up the plans, you have to make decisions about how things fit best and what works where, &c.
