Where on earth do you people get this money?

After all my bills are paid I have about ~$100 a month to use as spending money. I'd be in the red except I'm deferring my $40k student loan for the fourth year in a row.

Honestly though I think I'm making enough; I don't know what I'd do with myself if I made more. Pay off loans and then I dunno. Give it away to charity probably. I don't need anything aside from videogame money.
