Keep the desire to learn, and you will never be satisfied with what you have known. Always keep a curious mind to all the mysterious parts of the world. Keep the desire to learn, and whatever difficulties you face, the strong belief will support you in solving the problems. Keep the desire to learn, just as Ms Curie puts it: “Nothing in the world is to be feared, it is only to be understand.” So everything is possible if we try our best and never give up.
