Seneca

Don’t suffer imagined troubles. It’ll either happen or it won’t. Don’t suffer before you need to.

Marcus Aurelius

Don’t be over heard complaining. Not even to yourself.

Epictetus

Don’t compare yourself to others.

Seneca

Don’t tie your identity to things you own. Those things are fragile and can be taken from you at any moment.

Marcus Aurelius

You mess up too, so don’t judge other people.

Zeno

Don’t talk more than you listen. Two ears, one mouth.
