I took to truck driving because I’d had enough of working in a (salaried) profession where it was expected you would work weekends, bank holidays and long hours (without remuneration) simply to keep up with those other professionals who had no life outside of work 
I wanted to be able to walk away from work at the end of the day and have time to myself. There are times I miss the intellectual environment of my previous career, but on days like today when my time is entirely my own, I don’t miss it at all
