Earn cash back for shopping. Earning cash back on your purchases is a smart idea, and credit card rewards aren’t the only good cash-back strategy out there.

Many frequent shoppers also love the Ibotta app, which lets you earn cash-back on every purchase.
Enjoy making silly videos? Even short, silly videos can sell products online. Find an product worth promoting that has an affiliate program, then target your video toward potential customers of that product. In your video summary on YouTube, place your affiliate link for the product, and after the video, do a 30-second still frame showing a short URL where people can buy the product. If your video is funny, informative, or useful, you may sell some products. Big tip: Try to promote a product that makes you a fair amount of money for each sale, but doesn’t cost a whole lot for the potential customer. You can find products on Commission Junction, for one.

Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Amazon will have you work on micro-projects that require some sort of human interaction. Tasks can include translating a paragraph into English (or another language), rating the search results for certain keywords, or reworking an article. The tasks are simple, and you will be paid a small amount to complete each. But if you do enough tasks quickly, you can make a respectable amount of money.
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!

Make sure you’re using a high-enough quality camera (most smartphones will work but I’d suggest at least having a tripod so your footage isn’t shaky), but don’t worry about being perfect at first. The beauty of YouTube is that you can continue to test out different content and styles as you find what works for you. Instead, stick to a regular schedule to build up your subscriber base.

Once you’ve gathered a list, put together a template outreach email (as you’ll be doing this over and over) that’s short and clear with expectations. Tell your potential interviewee who you are, what your podcast is about, and what you’re asking of them. Do a few test interviews with friends and family to make sure everything is being recorded at the quality you want and then book your first episode.
