Just that you do the right thing. The rest doesn't matter.
What makes this formulation so bracing is that Marcus Aurelius isn't offering moral comfort—he's offering *permission* to stop worrying about outcomes. Most of us agonize over whether our right action will succeed, impress others, or yield the results we hoped for, as if righteousness were somehow incomplete without vindication. But the Stoic emperor is saying: that anxiety is a waste of your one life. When you refuse a bribe at work, the ethics are done; whether the company collapses or thrives afterward is genuinely none of your business. He's not being cold about it—he's being liberating, cutting away the psychological weight we insist on carrying.
