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.

The people have a right to the truth as they have a right to life, liberty and the pursuit of happiness.

You are but an appearance, and not absolutely the thing you appear to be.

Don't explain your philosophy. Embody it.

Authentic happiness is always independent of external conditions. Vigilantly practice polite indifference to that which we can't control. Your happiness can only be found within.

Be free from grief not through insensibility like the irrational animals, nor through want of thought like the foolish, but like a man of virtue by having reason as the consolation of grief.

What matters most is what sort of person you are becoming. Wise individuals care only about whom they are today and who they can be tomorrow.
