If you’ve sold on eBay for a little while, pretty soon the question will come up, “What do I sell?” You need to think about what product category you want to sell in. Since there are thousands of categories, you have many options to choose from.

Back just a few short years ago, I was getting started. I didn’t know what I wanted to sell. How did I decide? Well, let me tell you a bit about me. I’m a gadget geek. I know what electronics are going to come out before they do. I watch the gadget blogs. I keep tabs on what Apple is doing, and know when they are going to upgrade their iPhones. It’s a hobby of mine.

It wasn’t hard to go from my gadget hobby to selling gadgets on eBay. I sold my PlayStation 2. I sold a Gameboy and some computer games. It was easy because I knew electronics was my forte. After I ran out of things to sell around the house, I found an electronics wholesaler. They had webcams and computer accessories, and we still sell those to this day.

What are you interested in? What are your hobbies? Think about how you you can use your hobby to your advantage on eBay. Selling what you like will make your research and product buying a whole lot easier. Why? You’ll spend a lot of time researching and talking to suppliers, but it won’t seem like “work” to you. (And, as an added bonus, if you sell what you like, you’ll always have the latest and greatest item you can use for yourself too.)

The great thing about eBay is that nothing is fixed in stone. If you have no idea what you want, don’t be afraid. Just try something and see what happens. You can always change later if you don’t know for sure. The main goal is to just get started. Pick something and go.

Think about an airplane taking off from an airport. Does it always take off in the exact direction that it will end up? No. Most planes take off not pointed in the direction they eventually want to go, but when they are in the air, the pilot can make course adjustments. This applies to your business as well. Don’t worry if you take off in a different direction than you want to go. The main point when you’re a beginner is to get off the ground, and you do this by selling whatever you can at first. Once you’re in the air, then you can change the direction you’re going.

The most important thing you can do as a beginner is to just get going. If you choose to travel in too many directions at once, you’ll never get anywhere. Sell stuff around your house. Then once you’ve run out of stuff to sell, think about what you’d like to sell. Just choose something (maybe based on your hobbies) so you have a direction to move in.
