Give thy thoughts no tongue.

Read less, study less, but think more.

Speak only if it improves upon the silence.

Know well what leads you forward and what holds you back, and choose the path that leads to wisdom.

Long is the night to him who is awake; long is a mile to him who is tired; long is life to the foolish who do not know the true law.

The only true wisdom is in knowing you know nothing.
