Late for WHAT? "That matters."
. People start in college when they are 30 because it was a course they had to take. Mostly in Nursing, Dental Assistant, Mechanic, Welder, Computer programmer, Cook,carpentry & Aviation mechanic, Civil Engineer,other.
You got a leg up on other who did not take any training. However you did lose out on full time employment at a lesser job FOR THE REST OF YOUR LIFE. School time is nothing. 40 years is a long time, that you have to be exceedingly lucky or smart to make it to a comfortable situation come 60+(as work from someone else as an employee is harder to come by...when you are older.)
