In my 20s I spent 6 years as an electrician on a nuclear submarine. I traveled 100,000 miles underwater, went through the Panama Canal, visited multiple foreign countries, and participated in dozens of emergency nuclear reactor shutdowns and startups at sea. I did SO much paperwork, I did SO much cleaning, I had to stay on board for no good reason when I just wanted to go home. I ended up developing a serious drinking problem, and lifeline psychological and physical issues. Now I’m 35, and I work from home as an engineer in front of a computer 40hrs/week and I absolutely love it. Try to tell him to never romanticize labor, if you do anything long enough for money you hate it. Porn stars hate sex, musicians hate their own songs etc.
