I'm finally down from 5 jobs/hustles to just 2 now, soon to be one, and I'm looking forward to the free time. But I do these things:
1) Consulting for non-profits on database/technology (this is connected to my day job, and i'm at the point I turn down work 90% of the time)
2) Podcast- I have a 2 podcasts, one loses money, the other earns it.
3) Delivering bagels on the weekend- for a long time I delivered bagels on the weekend for a small bakery. Paid $25 for 1.5 hours of riding my bike. Plus free baggggeeellls.
4) Promo girl - kinda the worst, but I used to do "promo" for various beers/wines/liquors at bars on the weekend. Job: look hot, talk to douchebags, give them free booze. Pays decently for 2-3 hours of work but is soul sucking
