The only man who never makes a mistake is the man who never does anything.
Theodore Roosevelt

There can be no fifty-fifty Americanism in this country. There is room here for only 100% Americanism, only for those who are Americans and nothing else.
Theodore Roosevelt

Leave it as it is. The ages have been at work on it and man can only mar it.
Theodore Roosevelt

Absence and death are the same - only that in death there is no suffering.
Theodore Roosevelt

Great thoughts speak only to the thoughtful mind, but great actions speak to all mankind.
Theodore Roosevelt

The only time you really live fully is from thirty to sixty. The young are slaves to dreams; the old servants of regrets. Only the middle-aged have all their five senses in the keeping of their wits.
Theodore Roosevelt

Rhetoric is a poor substitute for action, and we have trusted only to rhetoric. If we are really to be a great nation, we must not merely talk; we must act big.
Theodore Roosevelt

I am only an average man but, by George, I work harder at it than the average man.

Government "help" to business is just as disastrous as government persecution... the only way a government can be of service to national prosperity is by keeping its hands off.
Ayn Rand

We are fast approaching the stage of the ultimate inversion: the stage where the government is free to do anything it pleases, while the citizens may act only by permission; which is the stage of the darkest periods of human history, the stage of rule by brute force.
Ayn Rand

It only stands to reason that where there's sacrifice, there's someone collecting the sacrificial offerings. Where there's service, there is someone being served. The man who speaks to you of sacrifice is speaking of slaves and masters, and intends to be the master.
Ayn Rand

Achievement of your happiness is the only moral purpose of your life, and that happiness, not pain or mindless self-indulgence, is the proof of your moral integrity, since it is the proof and the result of your loyalty to the achievement of your values.
Ayn Rand

The only power any government has is the power to crack down on criminals. Well, when there aren't enough criminals, one makes them. One declares so many things to be a crime that it becomes impossible for men to live without breaking laws.
Ayn Rand

The truth is not for all men, but only for those who seek it.
Ayn Rand

God... a being whose only definition is that he is beyond man's power to conceive.
Ayn Rand

Money is only a tool. It will take you wherever you wish, but it will not replace you as the driver.
Ayn Rand

Only the man who does not need it, is fit to inherit wealth, the man who would make his fortune no matter where he started.
Ayn Rand
