Sign up for a reputable affiliate network: Aside from Amazon, there are dozens of large reputable affiliate networks, such as Share-A-Sale, Clickbank, and Skimlinks, that specialize in connecting you with merchants who are looking for affiliates to sell their products.

Refinish old furniture from thrift stores, yard sales, or online ads. Sand down the furniture to smooth out the surfaces and buff off some of the old paint or stain. If you want to restain it, use a lacquer or paint thinner to remove the stain. Then, re-stain the piece. If you plan to repaint it, apply a primer and let it dry. Next, apply at least 2 coats of paint, letting each coat dry for at least 24 hours. If necessary, add new hardware to finish the piece.

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.
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
