Henry Ford said that all success and wealth first starts in your mind:
"You must never, even for a second, let yourself think that you can fail. Our first principle is that failure is impossible. If you shut out of your mind the possibility of being licked, then you are bound to win."
"One who fears the future, who fears failure, limits his activities. Failure is only the opportunity more intelligently to begin again. There is no disgrace in honest failure; there is disgrace in fearing to fail."
"Thinking is the hardest work any one can do, which is probably the reason why we have so few thinkers."
"If money is your hope for independence you will never have it. The only real security that a man will have in this world is a reserve of knowledge, experience, and ability."
My favorite Michael Jordan quote:
"Work ethic eliminates fear."
When you can look at the man in the mirror and know that you didn't cut corners, you spoke the truth, you've done the preparation, and you've lived in integrity with your chosen values, you are unfazed by anything in the external world, because you lived up to your own standard.
No esperes a sentirte preparado. Nadie lo está cuando empieza algo importante. La confianza no aparece antes de actuar; nace después de cumplir una promesa contigo mismo una y otra vez. Tu autoestima no depende de lo que piensas de ti, sino de las pruebas que le das a tu mente de que eres alguien que cumple.
Al final de tu vida no lamentarás haber trabajado duro por un sueño. Lamentarás las oportunidades que dejaste escapar por miedo, comodidad o procrastinación. El estoico no busca una vida fácil. Busca una vida que, al mirar atrás, pueda considerar digna de haber sido vivida.
