A blind man visited his relative. After dark, his relative kindly lit a lantern for him and said, "It's late and the road is dark. You can go home with a lantern!" The blind man was furious and said, "You know I'm blind, but you still light a lantern for me to light the way. Aren't you making fun of me?" His relative said, "You made the mistake of limited thinking. You are walking on the road, and many people are also walking on the road. If you hold a lantern, others can see you and won't bump into you." The blind man thought, that's right! This story warns us that limited thinking is thinking from your own perspective, and holistic thinking is to put yourself into the whole environment. If you think about problems systematically, you will find that your behavior will interact with others.
