"Anyone who stops learning is old whether at age twenty or eighty. Anyone who keeps learning stays young. The greatest thing in life is to keep your mind young"
It is important to expand your mind. There is a saying that ignorance is bliss. I say the opposite. There isn't anything positive or blissful about being ignorant to everyday life. Don't sell yourself short or allow your mind to grow old because it's not being used to its best abilities. Feed your mind and keep it young, it's the only one you have. Common sense isn't so common and you don't want to find yourself on that side of the field.
