Theodore Roosevelt

The relentless reformer who made himself strong through sheer will — and prized action above all.

4 min read · 1898–1919

Part I — The story

The story

Theodore Roosevelt was a force of nature — a sickly, asthmatic child who rebuilt himself into a rancher, soldier, explorer and the most energetic president in American history. His life was a testament to self-creation through sheer will and 'the strenuous life', and his presidency to vigorous action: breaking up monopolies, protecting vast wildernesses, and projecting American power.

Roosevelt prized doing over talking, famously honouring 'the man in the arena' — the one who actually attempts things and dares greatly, even at the risk of failure, over the critic who merely watches. He read voraciously, wrote prolifically, and threw himself at every challenge with total commitment. His combination of intellect, energy and bias toward action makes him a model for anyone who values building over criticising.

'The man in the arena'
His creed of daring action

Roosevelt embodies a bias toward action, self-creation through will, and the courage to dare greatly. His celebration of the doer over the critic — the person who enters the arena and risks failure — is among the most motivating philosophies in public life.

Part II — The playbook

The playbook

Principle 1

Dare greatly

Roosevelt honoured the doer who risks failure over the safe critic.

Do this: Enter the arena and attempt things; the credit belongs to those who dare.
Principle 2

Create yourself through will

He rebuilt a frail body and life by sheer effort.

Do this: Shape yourself through deliberate, willed effort rather than accepting your start.
Principle 3

Bias toward action

He prized doing over talking in everything.

Do this: Default to action; a decent plan executed beats a perfect one debated.

In their words

The credit belongs to the man who is actually in the arena.
Do what you can, with what you have, where you are.
Comparison is the thief of joy.
