See yourself confident!
If you do not have much confidence, this is one of the things that you need to change in your life. As a Entrepreneur what you think of yourself effects your business.
You do this by learning the reasons why you think and do things you do, reading self help book is a great place to start and listen to good uplifting audio podcasts. Some of my favorites is Joyce Meyer and Terri Savelle Foy.
And then know You Are Valuable to God!
