I had 2 day jobs, testing out what it is to be 'normal'. I also had electronics in school, so I repaired telephones and I was a Cable TV Field Engineer. Each day job lasted a few years while still gigging on the weekends.
I found out for me, normal is soooooooooo overrated. I bad day playing music is better than a good day at any day job I can imagine.
My first gig was when I was in Junior high school. I was in school band and after hours in a little rock band. We were terrible (everybody was back then). We got a gig playing for a junior high school dance. There I was on the stage, with my very best friends, playing the music we worked so hard to learn, and much to my surprise, that cute girl who wouldn't even acknowledge my existence in English class was 'making eyes' at me! And at the end of the evening, they actually paid me for that experience!!!!!!!!!
I went on the road after school, played in singles bars, mostly college towns all over the eastern 2/3 of the lower 48 US states. Partied a lot of beautiful women, had a lot of fun on stage, and saw a quite a bit of the country. Eventually we were the opening act in concert for the hit-makers of the day, The Four Seasons, The Association, The Kingsmen, etc., and eventually Motown. Here I was being treated as an equal peer by some of the most famous musicians on the planet.
The Motown recording deal fell through because Motown wanted to pay us only $0.02/record, and out of that came inflated recording, distribution, and promotion costs. Our manager figured we'd have to sell a million copies of our first LP to end up not owing Motown money. They picked their second choice to be the first white band on the Motown family of labels, The Sunliners. Of course, Motown has to own the band's name so they have complete control andthe Sunliners changed it to Rare Earth.
That's whey I tried my first day gig. But the lure of the stage got me back into music. (I actually feel better about myself as a musician than I did as an engineer.)
Since then I've played singles bars, show clubs, 5 star hotels, cruise ships, eventually slowly downsizing to my present duo that I formed with a band-mate (who is now my wife) when the last real 'band' had problems.
Sine then we've worked steadily, smaller venues, (yacht clubs, country clubs, retirement developments, private parties, etc.) not as much glory but more money per gig. And since I have the best woman with me, I don't need to chase skirts anymore.

We've had people who vacation here in places from Canada to Australia invite us to their homes and we've taken one in Australia up on that for two nights.
I'm past retirement age, and I have no plans to do so. Being a musician is what I am, not what I do. I can't imagine a live without gigging. It's the most fun I can have with my clothes on.
I probably would have made more money if I kept the CATV Engineering job, but I wouldn't have had such a happy life so far. I'm not rich, and I budget money, but my house is paid off, I've vacationed From Alaska to Costa Rica, from England to China plus North Africa, Australia and The Caribbean. I buy new cars (dodge class, not benz) but drive them until the become undependable (usually over 200k miles).
And I'm living my life on my own terms, not answering to some middle manager in a faceless corporation. I'm making my own decisions, and either profiting by them or learning by them.
I am glad I am making a life doing music and nothing but music.
Of course it's not right for everyone, and probably not right for most people, but it is right for me.
