A man is the sum of his actions, of what he has done, of what he can do.
Malraux isn't merely saying we're judged by our deeds—he's insisting that action itself *constitutes* identity rather than merely expressing it. The distinction matters: you don't have a fixed self that produces actions; instead, you become real through what you do and what remains within your capacity to do. This is oddly bracing for anyone trapped in regret or paralysis, because it means your past failures don't define you unless you've surrendered your ability to act differently. A person who spent years in the wrong career isn't ruined by that time if they still possess the power to choose anew—that latent capacity is as much "them" as their actual history.
