Philosopher Hegel once said that if you don't understand a certain truth on the road to becoming a human being, life will arrange a setback for you. If you don't understand this time, it will arrange another setback until you understand. This tells us that it is necessary to actively deal with setbacks so as to realize the true meaning of setbacks earlier. Recently, I watched an experiment in which two balls of the same size were released at the same distance. The difference is that one ball passed through a smooth surface while the other ball passed through a tortuous surface. Unexpectedly, the ball rolling on the tortuous surface of the road reached the end first. I think what this experimenter wants to tell you is that setbacks in life often make people grow up, and only after growing up one after another can they reach the end of success faster.
