我看到了，我忘记了；我听到了，我记住了；我做过了，我理解了。

The ability to be alone is the ability to love. It may look paradoxical to you, but it’s not. It is an existential truth: only those who can be alone are capable of love, of sharing, of going into the deepest core of another human being—without possessing the other, without becoming dependent on the other, without reducing the other to a thing, and without becoming addicted to the other.

O homem só é verdadeiramente livre quando reconhece a sua dependência dos outros.

未来是自己开拓的。
