All who know their own minds know not their own hearts.
It is as easy to unknowingly deceive yourself as it is to deceive others.
The mind cannot long play the heart's role.
We are very far from always knowing our own wishes.
If it requires great tact to speak to the purpose, it requires no less to know when to be silent.
Why can we remember the tiniest detail that has happened to us, and not remember how many times we have told it to the same person.
