Been in the skilled trades (diesel mechanic) for 19 years now. Skilled trades are great, good money, minimal investment in education, and easy to get a job. Something to keep in mind, most coworkers of mine have plans for what to do if/when there knees or back go out. So I guess great jobs that can potentially last for your whole career, but it’s not a bad idea to have a plan b in case your body says your done before your 401k says you are.
