I was speaking to an entrepreneur today, trying to learn about his industry and sell him marketing services. The guy kept coming up with reasons not to grow. Even when I asked him, what if you had 20 more customers willing to spend $15K (his dream cust), he said he would have problems fulfilling those customers.
This guy does not have a growth mindset. Maybe that's by choice; maybe he is happy with the current revenue, which is fine.
But as a new entrepreneur, a growth mindset is essential. The best way I know to overcome this is to have a coach or even better a coach who has already built that kind of business you are trying to build.
