I find this to be a simple quote and short but it has a lot of power and the knowledge gained from it will help you become a consistent good person. You can not know anything that you have not experienced lots of people say they know lots of things but the people who know the most are not bragging, they have the experience to learn that knowledge is not something you have but something earned in time.
Being a humble person about your knowledge and experience is going to let you interact with others in a positive way and they will let you have some knowledge they have and you can all grow together.
Meditating on these ideas will allow them to come to fruition you must think good thoughts which will actually help your mind to want good things and help you bring them into your life.
