If it was within your power that you could change one thing about your life in order to make you a happier, more content person, what would you like to change?
I think I would have not taken the first job I had right out of college (which was the job I had while I was still in college). It lead to my current job of 19 years. Sounds great, but I have no retirement benefits so it's pretty much been a waste of 19 years. I should have either continued with my education or pursued other career opportunities.
