I make extra spending money on survey sites. I have made $50 in the past 10 days. Join Inbox Dollars. They give you $5 just for signing up, but there is a $30 minimum before checking out. Also, opinion outpost is great. The minimum for paypal is $10 I think. You can get that super quick. If you're interested please message me for my referral link.

Make a website and put AdSense on it

Or sell something or ask random people for a dollar until you get 10 of them...
