No pleasure has any savor for me without communication.

Experience has taught me this, that we undo ourselves by impatience. Misfortunes have their life and their limits, their sickness and their health.

In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.

Pride dwells in the thought; the tongue can have but a very little share in it.

Fear sometimes adds wings to the heels, and sometimes nails them to the ground, and fetters them from moving.

To know how to live is my trade and my art.

In general I ask for books that make use of learning, not those that build it up.
