How far should I go back?

I worked as a grunt for a company building towers for electric distribution in South Florida after graduation from high school. Then, I was in the Air Force until my Mom got sick. Then, I drove an ambulance and became an EMT. I did this for four years before going to the fire academy to become a firefighter for another five years. That takes my work life up to 1990. I’ve had a number of other jobs since then but the most fulfilling job was being a dad and a pastor from 2011 to 2019. Nothing else even comes close.
