Amazon makes it fairly easy to list and sell old books, games and devices on its marketplace. You can make more than just a few bucks If you have pricey textbooks from college. Be sure the books are in good condition. You'll get negative reviews if you attempt to sell books that are falling apart or games that are scratched up. Remember, be upfront about any defects, no matter how small they might be and no matter how few people might readily notice it.
To create your own blog, you don’t even need a web domain. You can start a completely free blog on either WordPress or Blogger. Each of these sites has its ups and downs, but you can’t beat the price. You generally want to keep blog posts between 150-500 words until you have a few dozen under your belt. Links between your blog posts encourage people to stay on your blog once they find it, increasing traffic. Once your blog is up, promote it on social media for the greatest effect.
