Theodore Roosevelt

“Believe you can and you're halfway there.”

“In any moment of decision, the best thing you can do is the right thing. The worst thing you can do is nothing.”

“Comparison is the thief of joy.”

“The only man who never makes a mistake is the man who never does anything.”

“Nothing in the world is worth having or worth doing unless it means effort, pain, difficulty.”

“Old age is like everything else. To make a success of it, you've got to start young.”

“Do what you can, with what you have, where you are.”

“It is not the critic who counts; not the man who points out how the strong man stumbles. The credit belongs to the man who is actually in the arena.”

“Speak softly and carry a big stick; you will go far.”

“People don't care how much you know until they know how much you care.”

“Keep your eyes on the stars, and your feet on the ground.”

“Far better it is to dare mighty things than to rank with those timid spirits who know neither victory nor defeat.”
