Know what you are selling.

Knowing what you are selling is important because you want to make sure you can sell it.
This might mean that you have to keep in mind the following things:

- Is what I am selling legal?
- Is there a need for my product or service?
- What are other selling the same product or service for?
- How fast do I want to sell it?

When asking the above questions and also others in your mind then you will ensure that you can sell your product or service more easily.
