Build an audience by teaching.
In the beginning of your business journey, no one knows you. And you don’t need to spend $100,000 for running ads; just speak, write, blog, tweet, teach what you do, share information, and tell the story of your success, and surely you will build a loyal audience. This is what famous chefs do. Emulate them. People like to know your little secrets. Be confident in what you’re offering, give a little away for free, and if you have created something special, people will return to you with money.
