It’s sometimes hard to comprehend just how much people love t-shirts. And with the right niche, marketing, and tools, you can create an online t-shirt business that makes you extra money online while you sleep. (Even Bloomberg and Forbes feature stories from entrepreneurs who've done just that.) Services like TeeSpring make it easier than ever to create a t-shirt drop-shipping business where they handle the sales, printing, and shipping, and you’re only responsible for design and marketing.

Become a mystery shopper. This means doing business with various establishments and rating their products and services without their knowledge. It may sound like cake, but remember that it requires discreteness, a good memory for detail (ex. the name of every individual who helped or served you), and enough cash for you to be able to pay for your shopping experience up-front and then wait to be reimbursed pending the approval of your review.
