Do we learn more from finding out that we have made mistakes or from our successful actions? I think people learn more from making mistakes because then people realize what they have done wrong and then would turn back to doing the right thing.
For example smoking. People generally are curious on what smoking is like, and they say, “Well, I’m going to try it once, it won’t hurt.” Then later, they realize that they have smoked more than once, and are then addicted to smoking. After they try hard to stop smoking, then they truly realize they have made a mistake and have learned a big lesson. On the other hand, if you never smoke (yes, that is good), then you would not have learned that lesson.
Another example is when you always go biking, whether the weather is sunny, or rainy. Then, even though at the time I don’t feel bad, in the future I might get sick. In fact, I did get sick, so this time I have been taught a lesson and won’t go biking when it is freezing and raining outside anymore. But right now, it is nice and sunny so I can go biking!
Sometimes, it is really good to never do something and be successful, but usually, we learn most if we realize we have made a mistake in our life.
