"One reason children are capable of joy is because they take almost nothing for granted. To them, the world is wonderfully new and surprising. Not only that, but they aren’t yet sure how the world works: Perhaps the things they have today will mysteriously vanish tomorrow. It is hard for them to take something for granted when they can’t even count on its continued existence."
William B. Irvine | A Guide to the Good Life: The Ancient Art of Stoic Joy
