Courage without conscience is a wild beast.

Boldness is not a virtue by itself; it is a force, and force takes the shape of whatever steers it. The same nerve that protects a stranger can bully one, depending on what the person holding it wants. This is why admiration for daring is a poor guide to character. What matters is not how fearless someone is but what they are fearless in service of.

When you feel most certain and most willing to push, that is the moment to ask who pays if you are wrong. Keep one person who is allowed to tell you no. Strength that can hear an objection is the kind worth having.
