Everybody in this world does make mistake, in fact not only once but on many occasion, but the learning from the mistake is much more important than committing a mistake. There is no such person in this world who is perfect, in others words i could say perfection does not exist. Mistakes do happen and gives us an opportunity to learn from it.
There are people who are very proactive in their life, they used to perceive their life very intensely and they have good intuition as well. These people generally have sense that "failure is good only if you recognize it and move on with learning". In fact such people perceive mistakes as part of process to the altitude of success.
If you learn from mistakes then you take cognizant of the fact that each failure is one step closer to success. When you are in a situation and you as the person as a character in that situation, then its difficult to stay objective and the character does whatever is right logically at a particular time. On the other hand there are people who are able to stay objective and at the same time they can foresee the big overall picture, assess the lessons before mistakes strike them.
So to summarize...."you might be able to learn better and faster when you start picking up lessons from other for more logical and practical matters. However..."there are certain mistakes in life you need to experience for yourself in order not to make them again. Most of the times there are less practical and more personal and emotional experiences.
