I was interested in fishing and was good at catching trouts in little streams in the middle of camp grounds around Los Angeles. After being in the Sea Bee's, I got into Arctic research on Ice Bergs, currents, etc. But I was bored working for the Universities and not pleased with their research which often was only to prove their point of interest or political point of view. So I went into teaching in the getto, Indian villages, etc. but did not like the administration. (liked the kids)
A friend talked me into going commercial fishing, and after 25 or so years have to retire I was the one of the oldest in the high seas fisheries. It was wonderful to make your own decisions and make all those mistakes. The hours, being up occasionally for 4 to 5 days straight was enjoyable, however, most of the time it was expected to work on deck and run the boat at least 22 hours a day. Any profits went back into the business and we were always in houck. Probably the only big mistake I made was not going to a larger boat 15 years ago, instead I opted to take my family in the summer salmon fishing on a 58' boat - but then I have a great family. I do not feel that you can do well in a business unless you put over 100% interest and 100% drive into that business.
As a retirement, luckly, I can now afford to play with a business and like you the gun business intriques me. So I am working on those skills - It just trying to figure out which ones I have and would enjoy doing. Oh! Yes! I will not be doing the 100% any more.
I think it is great if you can do your own thing
