Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young.

You can't learn in school what the world is going to do next year.

Life is a series of experiences, each of which makes us bigger, even though it is hard to realize this. For the world was built to develop character, and we must learn that the setbacks and grieves which we endure help us in our marching onward.

Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young. The greatest thing in life is to keep your mind young.

It’s very simple. As you grow, you learn more. If you stayed at twenty-two, you’d always be as ignorant as you were at twenty-two. Aging is not just decay, you know. It’s growth. It’s more than the negative that you’re going to die, it’s also the positive that you understand you’re going to die, and that you live a better life because of it.
