Get over the idea that only children should spend their time in study. Be a student so long as you still have something to learn, and this will mean all your life.

You learn something every day if you pay attention.
Ray LeBlond

Sit down before fact as a little child, be prepared to give up every conceived notion, follow humbly wherever and whatever abysses nature leads, or you will learn nothing.
Thomas Huxley

Learning is a treasure that will follow its owner everywhere.
Chinese Proverb
