Generally, a mistake is a decision or an action that we come to regret. Mistakes usually cause some degree of pain, loss, or struggle. Certainly, we might agree that we don't like the consequences of a choice, and hence we call it a mistake. The irony is that these events, which we try so hard to avoid, may be precisely what we need to experience.
Most of us tend to try and avoid mistakes and view them as negative rather than important. But mistakes can teach us and help us improve.
Understanding the importance of mistakes and how to use them to our best advantage is what will develop us as a student, a parent, or a business man; as a human being wants to feel good.
Our mistakes are the adventures of us.
To truly rediscover the wonder of this world, we need to step outside the "tiny, terrifying space of rightness" and admit we might be wrong. Because once we can do that, we can see the whole big universe of information out there that we don't know.
