It always amazes me when people ask me that question or the variations listed below:

• How long did it take you to be successful?
• When did you earn your first sale?
• How many hours do you spend and how much do you make?
• If I put in x hours per day, how much can I make or when can I expect to be successful?

Depending on where you are in your business, you've either asked these same questions or have heard variations of them.
