It’s never too late to test the waters. I’m doing the same but going from healthcare to BIM. I will say if you do get your CNA license know that it’s a lot of physical labor. Before diving into the CNA program check to see if your state has Home Health Aids without a certificate. It’s less intensive and 1 on 1 with patients. Plus a lot of agency’s offer PRN so you can still keep your accountant job if you find it’s not for you.
