You must have an open mind to learn in order to be a successful entrepreneur. Learning leads to growth. Regardless of one's field of expertise, one should never consider themselves perfect.
In order to keep up with the growing technology, you should learn how to improve yourself and your business.
According to the saying;
Never stop learning, for when we stop learning, we stop GROWING
A willingness to learn can open up many doors of success for you, but if you restrict yourself from learning, you will never grow as an entrepreneur. You can bring more innovation to your business idea the more you learn.
