I have been in the concert business for 52 years. In Jr High I walked by the shop class every dad and always peeked in the window. The teacher often had his shop students work on his race sports car in class. The teacher was on the Chapparral team that won Sebring 12hrs in 1965.
I pleaded with my parents and school advisors to let me take shop class. They said NO, colleges ignore shop class credits.
So I went to Georgia Tech for Mechanical Engineering. Built and raced go karts at the Annual on campus Tech 200. They were in some ways the early beginnings of the now nationally College contested SAE competition. Attended a number of concerts at Tech, Chicago, Grand Funk, etc found that industry rather fascinating. I have no special fondness for music, but the rush of the raw energy from the interaction of the band and the audience when they take the stage is rather addicting, knowing all your efforts behind the scenes made it technically possible. I left Tech started my own production company, designed, innovated, built a full machine/wood shop and built most my own equipment in every facet of the industry, was always my own boss, played by my rules, traveled 37 countries, 47 states, made more money at the shows than everyone except the bands and sometimes the promoters, I have only paid to attend 3 concerts in my life, and have worked many thousands, never had two days alike, and retired with a very positive solid reputation and my integrity intact and probably have the best safety record of anybody in the industry. I likely have been very lucky and blessed. I have never been bored. Now being retired I have more projects than ever, and no concern if I finish any of them. Life is too short to worry about that.
Any secret I had, I was never afraid of failure as much as I worked to avoid it, and perseverance usually pays off, but changing direction always has to be an option.

PS, I need to add, any success I achieved was with many others right alongside me busting their butts for a shared dream, and I can never thank them enough
