“Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great.”
― Mark Twain

“With everything that has happened to you, you can either feel sorry for yourself or treat what has happened as a gift. Everything is either an opportunity to grow or an obstacle to keep you from growing. You get to choose.”
― Wayne W. Dyer

“If there is no struggle, there is no progress. Those who profess to favor freedom, and yet depreciate agitation, are men who want crops without plowing up the ground. They want rain without thunder and lightning. They want the ocean without the awful roar of its many waters. This struggle may be a moral one; or it may be a physical one; or it may be both moral and physical; but it must be a struggle. Power concedes nothing without a demand. It never did and it never will.”
― Frederick Douglass, Frederick Douglass: Selected Speeches and Writings

“Folks are usually about as happy as they make their minds up to be.”
― Abraham Lincoln
