The Power of Ideas
Ideas have great power in the world. Many great changes come from simple but brave ideas. Some famous thinkers and scientists, for example, Galileo and Lu Xun, had new thoughts that few people believed at first. But finally their ideas changed history.
In my opinion, we should learn to think independently. Don’t be afraid to have new ideas. Even a small good thought may make a big difference one day. Let us use our mind and create more wonderful ideas.
