My 10-year-old son brought home a book from our park’s free library box. It was a biology textbook – teachers edition. He said it looked interesting and hey, it was free (having no idea you could sell it). I scanned it in my Amazon seller app and realized it was worth around $150. He was so excited. We listed it for sale for $130 and it sold! Going to tell him, he just made $130!
Websites like Care.com connect parents with babysitters. The company does all the background checking and other due diligence to put parents' minds at ease.

Redefine wealth. In studies of millionaires, people are surprised to learn that most millionaires aren't doctors, lawyers, and corporate leaders with big houses and fancy cars; they're people who religiously live below their means and invest the surplus into assets, rather than liabilities.[3] As you're taking the above steps to make more money, keep in mind that increased income does not necessarily equal increased wealth. Most people who flaunt their wealth actually have a low net worth because their debt to asset ratio is high--in other words, they owe a whole lot more money than they actually have. All of the previous steps have outlined aggressive strategies for making money, but you'll never get anywhere if you have a hole in your pocket.

Look into survey sites like MyPoints, Survey Junkie or Vindale Research where you’ll get paid just for taking surveys and giving your opinion. Sounds like a pretty sweet deal, right? Just remember, these sites are looking for specific criteria. So you might have to wait for the right survey to come along that you qualify for. Plus, you’ll have to reach a certain threshold before you can cash out your points. It’s not a get-rich-quick opportunity by any means, but that extra cash can still add up over time. If you’re the patient and persistent type, give it a shot!

If you’ve got some free time and don’t live in the middle of nowhere, becoming a Lyft driver can be a very lucrative side hustle that allows you make money fast. And right now, they’ve got a promotion going on where any new driver will instantly get a $300 bonus after completing their 100th ride. If you start now and hustle hard on the weekends, you can probably unlock that bonus within a few weeks of driving (and that’s in addition to your normal earnings).
