Once you really focus your efforts on one method and stop jumping from one thing to another, you will soon start to see results. And once you see results, motivation will take over from there and you will just keep going. The problem for most people is that they give up usually right before they see results.

You just upload the design, choose the items you want your design to be on, and they’ll handle the rest (i.e. manufacturing, payment, shipping, and handling, returns…).
