This was a gift from the ex-president Teddy Roosevelt.

Believe you can and you're halfway there.

Yet there was no doubt that Theodore Roosevelt was peculiarly qualified to be President of all the people. Few, if any Americans could match the breadth of his intellect and the strength of his character. A random survey of his achievements might show him mastering German, French, and the contrasted dialects of Harvard and Dakota Territory; assembling fossil skeletons with paleontological skill; fighting for an amateur boxing championship; transcribing birdsong into a private system of phonetics; chasing boat thieves with a star on his breast and Tolstoy in his pocket; founding a finance club, a stockmen's association, and a hunting-conservation society; reading some twenty thousand books and writing fifteen of his own; climbing the Matterhorn; promulgating a flying machine; and becoming a world authority on North American game mammals. If the sum of all these facets of experience added up to more than a geometric whole - implying excess construction somewhere, planes piling upon planes - then only he, presumably, could view the polygon entire.

We have the right to demand that if we find men against whom there is not only suspicion, but almost a certainty that they have had collusion with men whose interests were in conflict with the interests of the public, they shall, at least, be required to bring positive facts with which to prove there has not been such collusion; and they ought themselves to have been the first to demand such an investigation." -Teddy Roosevelt

If this country is really to go forward along the path of social and economic justice, there must be a new party of nationwide and non-sectional principles, a party where the titular national chiefs and the real state leaders shall be in genuine accord, a party in whose counsels the people shall be supreme, a party that shall represent in the nation and the several states alike the same cause, the cause of human rights and of governmental efficiency. At present both the old parties are controlled by professional politicians in the interests of the privileged classes, and apparently each has set up as its ideal of business and political development a government by financial despotism tempered by make-believe political assassination. Democrat and Republican alike, they represent government of the needy many by professional politicians in the interests of the rich few. This is class government, and class government of a peculiarly unwholesome kind.

He was very impressed with Theodore Roosevelt, and Teddy Roosevelt used to say 'you have to get into the fray,' and that was sort of a motto of his.
