The internet is full of stories about people who make a killing selling merchandise such as T-shirts online. The short news articles always make the process seem so easy.

What the news blurbs fail to mention is the amount of work the entrepreneur they’re featuring did before they became a success. The key is knowing how to have the right mindset for selling T-shirts online.
