To be getting an education means this: to be learning what is your own, and what is not your own.

Keep silence for the most part, and speak only when you must, and then briefly.

It’s time to stop being vague. If you wish to be an extraordinary person, if you wish to be wise, then you should explicitly identify the kind of person you aspire to become.

Practice yourself, for heaven's sake, in little things, and thence proceed to greater.

To the rational being only the irrational is unendurable, but the rational is endurable.

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.

What concerns me is not the way things are, but rather the way people think things are.
