Ask yourself what you wanted to be when you were a kid. The answer may be more telling than you would think.
Also, there are career/personality tests out there, often administrated by community colleges. Tests like Myers-Briggs and the Strong Interest Inventory can point you in a fairly accurate direction. Two drawbacks are that they do cost money and you still have to make the hard decisions. I took one of these my senior year in high school. I ignored the results because I didn’t believe any mere test could nail me down.
However, years later, I took the two tests noted above and found that the top three professions highlighted in high school were the same three highlighted for me as an adult. As an adult, I was interested in all three. If I had paid attention to this information out of high school, I would be making serious bank and my husband would be a kept man playing his music out each night instead of working a day gig.
Instead, I have meandered through many professions and titles. My favorite being “Knowledge Librarian.” Additionally, I have been a travel agent, an administrative assistant, an environment and emergency response writer/editor, a software tester, a mortgage banker, a corporate intelligence researcher, and a paralegal. I am currently a free-lance writer and a student working temporary jobs. (Which might be something you do to get exposed to different kinds of jobs.)
It sounds like you are more of the “handy-man/out-doorsey” kind of person. Note that formal school isn’t necessary in having a satisfactory or decent paying job. Trade organizations (electric, plumbing, etc.) are excellent ways to work into a profession while learning. Also, as I am sure you are aware of by now, there are pros and cons to working for others, as well as being self-employed. Keep your mind open to all possibilities.
One last thought:
In your quest for, “enlightenment and truth” remember the saying; “To thine own self be true.”
P.S. Sorry if this is all a little disjointed on the advice side. I had some surgery recently and I’m still on painkillers.
