Act your part with honor.

And have you not received faculties which will enable you to bear all that happens to you? Have you not received greatness of spirit? Have you not received courage? Have you not received endurance?

Ask yourself: Does this appearance (of events) concern the things that are within my own control or those that are not? If it concerns anything outside your control, train yourself not to worry about it.

It's not what happens to you, but how you react to it that matters.

The cause of all human evils is the not being able to apply general principles to special cases.

The key is to keep company only with people who uplift you, whose presence calls forth your best.

Don't be concerned with other people's impressions of you. They are dazzled and deluded by appearances. Stick with your purpose. This alone will strengthen your will and give your life coherence.
