If we go through our days with a closed mind, we won't be able to function very well.
We learn and grow from having an open mind. None of us know everything, and the old saying stays true, "The more you know, the more you realize you don't know."
So have an open mind, boo! You never know what you might learn out there in this fabulous world we're in! There's information galore to soak in. Keep growing, glowing, and learning.
