Many people fancy themselves as designers. If you have a unique idea for a new product then it may be time to get it designed. This can be a long process involving prototypes, discussions with factories, package design, and much more. However, the profits once the product is on the market could be substantial. And remember, with Amazon FBA, your products can all be stored and shipped by Amazon, giving you time to think up your next invention.
How much will you make? I think my best month with Google AdSense was almost $5,000 over the last ten years. That amazing month blew my mind since it was actually near the beginning of my blogging journey. When you go from making zero to $5,000 in a month, that will rock your world. For me, it also got me even more excited because I knew there were other ways to monetize.
