Tommy Landry of Return on Now, explains this transformation. "One of the major changes to 'how we work' over the past decade is the massive shift toward free agency, i.e. freelancing, consulting, or running solopreneur-types of businesses," he says. "While many older workers were taught to pursue security in the form of a full-time job, that is no longer the only way to make a living. In fact, it has become super easy to make the leap out to independence heading into 2019. You could consult or freelance in a number of areas from copywriting to marketing strategy, or run your own ecommerce business from your home."
I’d stick with Amazon if I were you. All of my Amazon sites only have Amazon affiliate links. If you use Google Adsense display ads on your site, you’re literally taking people away from your site for the sake of just a few cents with these type of ads. If you direct them just to Amazon, then you have a greater chance of earning more money from that click.
Hunt for under-priced used books that you can sell online. Download an app that reads ISBN numbers so you can scan the barcodes on books. This will pull up the book’s current price on Amazon so you can see if it’s worth trying to resell it. Then, visit used book stores, thrift stores, and garage sales to look for high value books. Post the books for sale online using sites like Amazon or Ebay.
