One of the main ways to ensure that your business does not reach a point where it stops growing is to learn how to think differently. Your role in your business should change over time.
Ideally, you should go from a salesperson to a business person.
As a salesperson, you thought much differently than you will as a business person. The mind of a business person is always on top of everything in the business. You will start to work hard at growing your business and reaching success.
Do not get stuck thinking that if you are a good salesperson that is all you need to be. You must master being a good business person in order to take your business to the next level.
