After a few days of sea sickness, hard work, lack of sleep, and fear I probably would have shot myself if someone had given me a loaded pistol.
Nothing I did since then (and I had summer jobs while I was a student doing things like weeding large fields of barley, digging ditches etc.) was anything like that.
So I learned to have a LOT of respect for people who don't have the chance to make lots of money sitting at a computer for most of the day.
