There are actually more deals out there like this than you'd believe, thanks to the fact that sellers list used textbooks for low prices on Amazon all the time, not realizing they could trade that book into Amazon for more money. For example, you might see a Biology 101 textbook that has a used price of $45 and an Amazon trade-in price of $70 – meaning you could buy it and trade it right back in for about a $25 profit.

One of the more challenging jobs in customer service this involves reaching out to clients who have unpaid bills, invoices, loan instalments or any other outstanding payments. Collections agents are responsible for creating lists of debtors and organising them based on how severe the matter is, getting in touch with customers and discussing how the debts may be collected, locate unresponsive customers using credit bureau information, perform background checks, etc.

Since time is the most precious commodity on this earth, invest the time at the front-end so that you can reap the benefits on the back-end.

And you'll continue getting paid whether you keep building that passive income stream or you stop. It's obvious that this is the preferred route, but clearly the road less traveled.
Mobile applications are more popular than ever, and people are willing to pay good money for ways to manage their lives from their smartphones. If you have a great idea and happen to know coding, you can run with it and create your app yourself.
