"Dark and Difficult times lie ahead, Harry. Now is the time that we must choose between what is right, and what is easy."
(Dumbledore, Harry Potter and the Goblet of Fire, 2005)
"To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment."
(Ralph Waldo Emerson)
"I have walked that long road to freedom. I have tried not to falter; I have made missteps along the way. But I have discovered the secret that after climbing a great hill, one only finds that there are more hills to climb. I have taken a moment here to rest, to steal a view of the glorious vista that surrounds me, to look back on the distance I have come. But I can rest only for a moment, for with freedom come responsibilities, and I dare not linger, for my long walk is not yet ended."
"Knowledge wants to be libre."
"Be the change you want to see in the world."
"Learning is finding out what you already know. Doing is demonstrating that you know it. Teaching is reminding others that they know just as well as you. You are all learners, doers, and teachers."
(Richard Bach, Illusions)
"I don’t know what I may appear to the world; but to myself I seem to have been only a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me."
and last, but not least:
"The teacher [who] is indeed wise does not bid you to enter the house of his wisdom, but rather leads you to the threshold of your own mind."
