Teddy Roosevelt

“It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.”

Thomas Edison

"Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time."

Plutarch

"What we achieve inwardly will change outer reality."

Viktor Frankl

"Everything can be taken from a man but one thing: the last of the human freedoms — to choose one's attitude in any given set of circumstances…Between stimulus and response there is a space. In that space is our power to choose our response. In our response lies our growth and our freedom."

James Clear

"New goals don't deliver new results. New lifestyles do. And a lifestyle is a process, not an outcome. For this reason, your energy should go into building better habits, not chasing better results…Every action you take is a vote for the type of person you want to become.”

Richard Hamming

"Knowledge and productivity are like compound interest. Given two people of approximately the same ability and one person who works ten percent more than the other, the latter will more than twice outproduce the former. The more you know, the more you learn; the more you learn, the more you can do; the more you can do, the more the opportunity – it is very much like compound interest. I don't want to give you a rate, but it is a very high rate. Given two people with exactly the same ability, the one person who manages day in and day out to get in one more hour of thinking will be tremendously more productive over a lifetime…I think it is very definitely worth the struggle to try and do first-class work because the truth is, the value is in the struggle more than it is in the result. The struggle to make something of yourself seems to be worthwhile in itself. The success and fame are sort of dividends, in my opinion."

Seneca

"We suffer more in imagination than in reality."

Jerzy Gregorek

“Easy choices, hard life. Hard choices, easy life.”

Ben Franklin

"Dost thou love life? Then do not squander time, for that's the stuff life is made of."

“Search others for their virtues, thy self for thy vices.”
