“I don’t know what to sell or even where to begin…”

It can be hard to decide what to sell as there are many lucrative options.  My suggestion is to start with something that you love.  Write down a list of products that you buy regularly. Look into selling those types of products. Use your reverse search to make sure you have an online market for it.  It always best to start with something that you are passionate about because when the hours get late, and you become tired of educating yourself with the marketing techniques, it is that passion that will keep you going.
