Growing is not knowing.
Have you ever heard the phrase "knowing stands in the way of learning?" It is so true. The greatest learning phases always come into your life when you are open-minded.
Sometimes it's when you start school, start a new job, start going to a new church, start a new relationship, start a new hobby or sport, or have a child. The key common factor is open-mindedness, admitting that you don't know it all and openly desire to learn.
Hold onto open-mindedness in all things. The one thing we know for sure is that we don't yet know all things. In fact, we don't even yet know all that we don't know!
And remember: "Growing is NOT knowing!"
