Voted for Pay of bad debts.
Any money right now probably should go to paying off debt (though I don't have any that I would consider bad, just more than what I'm really comfortable with).
I can't think of a small business that I could pull off for $10,000, and while I'd be okay with investing in something, the debt is happening now and really should be lowered as soon as possible.
I could see myself going on a trip around the world and being a travel vlogger, though. I would probably need more than $10,000 to get all the way back around. :)
