I'm still a poor college student...
Here's what I've done:
Sold all of my parents unwanted things
Hired by people locally who were 'hoarders' and helped them snap out of it and get their life back together. That pays nice.
Babysit for doctors.
Things I'm considering doing once the debt hits hard in the face:
Nude Modeling for Art
Selling virginity (only if I still have it by 25, and if I can sell it for a million)
Maybe selling eggs? They go for 30k sometimes, but considering what I've done to my body, I don't think I could sell them.
