Do what is right
Principle 35 from the Enchiridion
Act respectfully without waiting for universal agreement. Once you have judged an action carefully, other people's approval is not what makes it right.
Original Passage
When you do anything from a clear judgment that it ought to be done, never shun the being seen to do it, even though the world should make a wrong supposition about it; for, if you don't act right, shun the action itself; but, if you do, why are you afraid of those who censure you wrongly?
Modern Interpretation
Epictetus asks for moral courage. If you have considered an action carefully and believe it is right, do not abandon it only because someone may misunderstand you.
The principle is simple: if the action is wrong, leave it. If it is right, do it calmly and accept that you cannot control every opinion.
This is not praise for stubbornness or pointless rebellion. Check your reasons and the likely effects first. After the judgment is clear, universal approval is not a requirement.
In Practice
Here is one everyday case. You set a boundary with a friend who repeatedly disrespects your time. Others say you are being selfish. You review your reasons and confirm the boundary is fair and necessary.
Explain the boundary calmly and respectfully. You do not need to write an essay in your own defense just to make everyone agree.

What do you believe is the right thing to do but keep postponing because someone may misunderstand it?
