First "job" came at 16. Family friend who was the preacher, teacher and did construction asked me at the super bowl party if I wanted to learn a career...thought about it for a day and said sure thing. That summer I went to work learning all sorts of things about construction and carpentry.
He was big on the Career not a Job aspect and took the time to show and teach me things the right way. Of course this ruined me for future work. Imagine at 16 having the boss look you in the eye and say "I have never and will never ask an employee to do anything I haven't, can't or won't do myself". Yeah that makes working for a big company later in life really hard!
Think I started at 6 an hour and 3 years later I was making close to 20, running job sites and working by myself when the boss was off doing bids. Was a great job and I dang near went into construction instead of healthcare. This time of year I really do miss roofing houses or building decks. Come winter or 90 degree days not so much.
