We can never know everything that there is to know about business. The world also moves on. We can also add that we often forget things that we have learned in the past.
For these reasons alone we need to continue to learn and educate ourselves about business. Take time each week to do some reading and research about business topics. You can do this by reading books, blogs and financial newspapers and journals. Sometimes just one sentence in an article can switch on a light in out head and give us a great idea or show us a way to do something better.
