A blind man went to visit a relative. After dark, the relative kindly lit a lantern for him and said, "It's getting late and the road is dark; you should carry this lantern on your way home." The blind man responded irritably, "You know I am blind, yet you give me a lantern to light my way. Are you mocking me?" The relative replied calmly, "You are making the mistake of limited thinking. When you walk on the road, there are many others around. By carrying a lantern, others can see you clearly and avoid bumping into you." The blind man realized the truth and thought, "You're right!"
The story teaches us that limited thinking is merely viewing things from one's own narrow perspective, whereas holistic thinking involves placing oneself within the entire environment. Through systemic thinking, you will realize that your actions interact with the world and the people around you.
