It’s a big risk to leave a stable job and venture out into territory unknown, which is exactly why many people decide to test the demand for their new business while still enjoying the benefits of a full-time salary. This works particularly well if the idea is new or you aren’t sure whether or not the product will go over well in your area. By not committing full-time to the business, you can maintain a safety net in case it doesn’t go as well as you hope.
I created an “Every Day I’m Hustling” shirt and sold enough for the campaign to ship, but didn’t earn much on the experiment because of some not-very-effective Facebook advertising.

If you can create awesome designs and reach the right people with good Facebook targeting, Teespring can be very profitable.
