“A round man cannot be expected to fit in a square hole right away. He must have time to modify his shape.”Mark Twain · Scrieri și caiete · 1897 · Scrieri și caiete, caietul din 1896–1897
Changing a person is a process, not a decision: shape reshapes over time, not overnight.
The shape metaphor says something about the pace of human change: we often demand instant transformation from others, as if personality were a reconfigurable object. Twain suggests that a person's shape is real and resistant, and adaptation is a gradual process, not a decision. A technical employee promoted to management does not become a leader overnight; they need months to reshape their reflexes.
Why it matters Useful in judging others and yourself: give time before judging how well someone adapts.
