Life is short. Save time climbing a ladder by going to college for four years.
So heres my story: i am 30 years old, i make a good living, i own a house and a nice truck (well the bank still owns most of both of those). i have always been interested in electrical and mechanical things... in high school, i hated my normal classes (i did OK in them, not great), but i loved shop, took woods for 2 years, metals for 1... wish i would have taken metals for 3 years instead. after HS, i went to college... luckily i got in to the state school about 6 miles from me (FIU), and i majored in electrical engineering -- with an emphasis on power systems. again, i hated my core classes (math, english, etc) but i did very well in the electrical and physics classes.
starting at 15 years old, i got a summer job with an electrician, making minimum wage as a helper. despite the poor pay, it was one of the best things that ever happened to me, in retrospect. i stayed with the company for about 8 years, i worked summers mostly, did the electricians helper thing for 2 summers, then moved to the other side of the company which did streetlights and utility repairs. i learned a LOT at that company and still use much of what i learned then. when i was 19, i built a generator out of an old forklift engine and a scrapped military generator, just because i wanted to. that experience would go on to help me land my current job.
ended up interning with the power company for 2 summers while i was in college, and had a job waiting for me once i graduated. for the past 6.5 years i have been a field engineer, i drive a van, i turn screws and wrenches, and yes, i even climb a ladder. i get to use a lot of my technical knowledge, and it is a very rewarding career, but they only hire degreed engineers for this position.
that being said, within my company, many of the union, non degreed positions make a TON of money, mostly because of the over time pay, but at the end of the year, its what you take home that matters, because we all work over time too and dont get paid as well.
if you have an interest, a passion, then follow it. find a way to make money doing it. work hard whether you have a degree or not, and it will pay off in the end.
