A man's true delight is to do the things he was made for.

One of the recurring themes in Marcus' handbook is leadership's responsibility to work intelligently with what it is given and not waste time fantasizing about a world of flawless people and perfect choices.

To live happily is an inward power of the soul.

If you are distressed by anything external, the pain is not due to the thing itself, but to your estimate of it; and this you have the power to revoke at any moment.

Stop whatever you're doing for a moment and ask yourself: Am I afraid of death because I won't be able to do this anymore?

Truth and ceremony are two things.

Everything is banal in experience, fleeting in duration, sordid in content; in all respects the same today as generations now dead and buried have found it to be.
