Directed attention results in precise and effective action. Divided attention results in clumsy and inconsistent action.

The Stoic Emperor

Anger, if not restrained, is frequently more hurtful to us than the injury that provokes it.

Seneca

Just stick to your principles. And rest assured that, if you remain true to them, the same people who made fun of you will come to admire you.

Epictetus

Remember never to say that you are alone, for you are not alone; nay, God is within, and your genius is within.

Epictetus

An honest thinker will highlight and confront the most intimidating counterargument. A dishonest thinker will seek out the most ludicrous counterargument and pretend it is the only counterargument.

The Stoic Emperor

What was hard to suffer is sweet to remember.

Seneca
