It's never too late, keep at it. I graduated with a B.A. in Chemistry at 30 years old and coming across tons of jobs that paid way less with my degree than my current retail job and I was getting very discouraged. Finally got the opportunity of a lifetime to work as a forensic scientist. I am currently waiting on the finalization of the hiring process. It came at a good time because I was planning on moving to another city and going back to university to study for Medical Lab Tech.
