Obstacles don't have to stop you. If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it, or work around it. 장애물 때문에 반드시 멈출 필요는 없어요. 벽에 부딪힌다면 돌아서서 포기하지 말아요. 어떻게 벽에 오를지, 뚫고 갈 수 있을지, 돌아갈 순 없는지 생각해봐요. (마이클 조던) An education isn't how much you have committed to memory, or even how much you know. It's being able to differentiate between what you do know and what you don't. (Anatole France)
