I'm curious about other people's side work/freelance projects. Do you have one? How easy/hard was it to get started?
I have a few:
Music gigs. I play keys and sing with a couple of bands. I was a music major and someone else has always taken the lead on booking gigs so it was pretty easy to pick up. The money varies from free beer to fifty bucks. We play originals, so if we switched gears to be a cover band, we'd make more money but it wouldn't be as fun.
Cat boarding. I love cats, and I offer crate-free boarding on the second floor of my house. Pretty easy, and beats having a roommate. I have three cats of my own, so what's a few more more mouths to feed and litter boxes to clean?
Landlording. I just rented out my old house last month. This wasn't particularly easy and requires much more of an investment than gigging or cat boarding. But it does pay better.
Jams/Jellies/Hot Sauce. (Future) We have quite a bit of land, so Mr. MP and I talk about actually harvesting something unique, making something with it, and selling the products at local markets. This is probably a few years down the road, but we'll need to plant soon if we're looking at tree-things.
Anyone else?
