It – How Churches and Leaders Can Get It and Keep It (2008, Zondervan)
“The best thing for being sad," replied Merlin, beginning to puff and blow, "is to learn something. That's the only thing that never fails. You may grow old and trembling in your anatomies, you may lie awake at night listening to the disorder of your veins, you may miss your only love, you may see the world about you devastated by evil lunatics, or know your honour trampled in the sewers of baser minds. There is only one thing for it then — to learn. Learn why the world wags and what wags it. That is the only thing which the mind can never exhaust, never alienate, never be tortured by, never fear or distrust, and never dream of regretting. Learning is the only thing for you. Look what a lot of things there are to learn.”

Variant translation: Just as the largest library, badly arranged, is not so useful as a very moderate one that is well arranged, so the greatest amount of knowledge, if not elaborated by our own thoughts, is worth much less than a far smaller volume that has been abundantly and repeatedly thought over.
Parerga and Paralipomena (1851), Counsels and Maxims

Variant: The more that you read,
The more things you will know.
The more that you learn,
The more places you’ll go.

Knox College commencement address (3 June 2006)
Context: But you have one thing that may save you, and that is your youth. This is your great strength. It is also why I hate and fear you. Hear me out. It has been said that children are our future. But does that not also mean that we are their past? You are here to replace us. I don't understand why we're here helping and honoring them. You do not see union workers holding benefits for robots.

Ki Sayings (2003)
Context: You must not think of what you learned as belonging to you. Your learning was only possible because of the people who taught you. If you forget this, before you know it you fall under the illusion that you are the only one who can do it, or the only one who understands. This is called being full of yourself. It is wrong to think, ‘I am strong’, because this strength is nothing but weakness turned inside out. You must think how to act within universal principles.
