As a child, Einstein did not appear particularly gifted. By the age of three, he still could not speak. When he started school at six, his performance was poor, and he was often criticized in class. Teachers even said he would never achieve much. People generally regarded him as inherently slow-witted.
However, by the age of twelve, Einstein had already decided to dedicate himself to exploring the mysteries of the vast universe. At fifteen, he was expelled from school because he failed subjects like history, geography, and languages, and his disrespectful attitude disrupted classroom order.
Einstein placed great importance on thinking and imagination. He once said, "Imagination is more important than knowledge. For knowledge is limited, whereas imagination encompasses the entire world, drives progress, and is the source of knowledge evolution." At sixteen, he often daydreamed, imagining himself riding a beam of light through space, and wondered: if there were a clock at the starting point, how would time appear to pass from my perspective?
From then on, he began his scientific journey. He designed numerous thought experiments and proposed models like the "light quantum," laying the foundation for the development of relativity and quantum theory.
Flexible thinking is crucial for personal success. Embracing the idea that "posing a question is often more important than solving one" allows individuals to continuously raise new questions and, in solving them, gradually reach the pinnacle of personal achievement.
