The easiest way to grow your customers is not to lose them
It’s difficult to stay focused on your business goals when challenges arise and your determination is tested if you don’t know why you’re doing something.
If you’re fortunate enough to have customers who are rooting for you and your business, you’re probably going to need to train yourself to politely thank them for their ideas and not implement them. If you try to implement every bit of input from your customers, you will quickly lose focus, and you could easily lose a lot more than that. The discipline you need in order to politely reject suggestions from well-meaning people varies widely depending upon your circumstances.
