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!

Getting a raise is an excellent move because it doesn’t require you to trade more time for more money. You are putting in the same amount of time, but pulling a bigger paycheck.

What’s the catch? None, really. Cash back apps act as affiliates for many online merchants, which means that whenever you make a purchase through one of the apps, they get a small commission — but then, they give you a portion of that commission as “cash back”. For example, if I buy a pair of Nike shoes through the Ebates app (or website) and spend $75, Ebates may get a $10 commission but then they’ll pass $7 back to me. It’s basically a way to get sale prices on stuff that isn’t on sale!

Outwardly, I live a very normal life, modest home, cars etc., however no one sees my portfolio of investments. In many ways, I exemplify the characterization in the book “the Millionaire Next Door”. I also do not share the specifics of my earnings with anyone. Regarding the flashy bragging types, I do not know any them personally, however I agree they’re insecure. Why else do they need other people to praise or envy them.
Keep in mind though, you don’t need a website to do sponsored content since you can also get paid if you have a lot of social media followers. My wife has a pretty big Instagram following, and she gets all kinds of sponsorships. Not only does she get paid in cash, but we get a lot of free stuff, too. We’ve received free rugs, free lights, and free carpet cleaners. She only promotes things she loves though, so this strategy works really well for her.
