What are some realistic new careers for a middle aged custodian? Just to give a little background, I am in my early thirties and have been a custodian since I dropped out of college a little over a decade ago. Recently, I have been feeling the need to challenge myself and make my lot in life a little better. I was wondering what careers fields I should realistically be looking at as a middle aged man with my history. Something with a two year degree would be ideal. Before I dropped out, I had strengths in mathematics, writing, and science. Thanks in advance.
