For outward show is a wonderful perverter of the reason.

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

Be tolerant with others and strict with yourself.

The stone that is thrown into the air is none the worse for falling down, and none the better for going up.

A man should always have these two rules in readiness. First, to do only what the reason of your ruling and legislating faculties suggest for the service of man. Second, to change your opinion whenever anyone at hand sets you right and unsettles you in an opinion, but this change of opinion should come only because you are persuaded that something is just or to the public advantage, not because it appears pleasant or increases your reputation.

So much worse are the consequences of anger than its causes.

If it's in your control, why do you do it? If it's in someone else's control, then who are you blaming? Atoms? The gods? Stupid either way. Blame no one. Set people straight, if you can. If not, just repair the damage.
