I’m a graphic designer tired of the creative industry. What career could be a new fit for me?

I currently have a job in graphic design. I’m feeling incredibly burnt out and am considering in the future what other paths I could take. I do NOT want to do anything in marketing or sales. I really want to get out of the creative job market and into something more grounded and straightforward.

Preferably would like to not have to go back to college but not entirely opposed. REALLY don’t want to though.
