As in walking it is your great care not to run your foot upon a nail, or to tread awry, and strain your leg; so let it be in all the affairs of human life, not to hurt your mind or offend your judgment. And this rule, if observed carefully in all your deportment, will be a mighty security to you in your undertakings.

Be careful whom you associate with. It is human to imitate the habits of those with whom we interact. We inadvertently adopt their interests, their opinions, their values, and their habit of interpreting events.

The universe is but one great city, full of beloved ones, divine and human, by nature endeared to each other.

Fortify yourself with contentment, for this is an impregnable fortress.

If what charms you is nothing but abstract principles, sit down and turn them over quietly in your mind: but never dub yourself a Philosopher.

Progress is not achieved by luck or accident, but by working on yourself daily.

To live a life of virtue, you have to become consistent, even when it isn't convenient, comfortable, or easy.
