You could always try selling commodity type stuff. Pick something you know there's already a market for like cell phone chargers or dry erase markers. Find a good supplier, preferably a drop-shipper (https://www.google.com/search?q=drop+shippers https://www.google.com/search?q=drop+shippers), and start selling. Start on Ebay and Craigslist to answer questions like "How much should it cost?", "Who is buying this stuff?", "Where should I promote my commodity?" Thereafter, it wouldn't be very hard to setup a Tumblr and then maybe build in Paypal or Stripe for payments. At the very least, you'll learn tactics to market whatever it is you're hoping to build. It can also help you develop a supply chain.
