I teach some music private lessons and play jazz gigs. An easy side hustle that should require not more than 10 years of work for a couple of hours a day to qualify if you apply yourself. You could be a hundredaire! :-)
"Jazz Musician": someone who puts a $10000 horn in a $1000 car to play a $100 gig
Can confirm, have made hundreds from playing music after four years of several hours a day. Still probably only made 25% the cost of instrument and strings though.
