"It’s not who you are that holds you back, it’s who you think you’re not.”
"Complaining does not work as a strategy. We all have finite time and energy. Any time we spend whining is unlikely to help us achieve our goals. And it won't make us happier." -- Randy Pausch, The Last Lecture
"All your life you are told the things you cannot do. All your life they will say you're not good enough or strong enough or talented enough; they will say you're the wrong height or the wrong weight or the wrong type to play this or be this or achieve this. THEY WILL TELL YOU NO, a thousand times no, until all the no's become meaningless. All your life they will tell you no, quite firmly and very quickly. AND YOU WILL TELL THEM YES."
