What is a very important skil a person should learn? What is a very important skill a person should learn in order to be successful in this world to day? As far as I am concerned, I contend that the skill should be the ability of introspection There are many reasons why introspection is the skill crucial to success, and I state some primary reasons as follows First of all, it is impossible for any person that never encountered failure in his or her life Since failure is the essential and unpleasant part of our life, what we should learn is the ability to overcome it Therefore, I deem the ability of introspection as the skill that we should learn, because it is the most effective way to overcome our failure By introspecting ourselves, we could find the reason that causes our failure and then we could learn from this failure As an old saying goes, failure is the mother of success Having the ability to introspect oneself means having the key to success Thus introspection is the skill to learn in order to success Secondly, we all know that success in one thing does not guarantee the success in another However, many people were still lost in this kind of confusion and finally lead to their failure To avoid this, we should learn the ability of introspection Because this ability could make as awake in every step we do, every decision we make, and this ability could guarantee our success in the long run Thus it is essential to learn the skill of introspection In conclusion, no matter it is success or failure that we encountered, we all need to introspect ourselves, because this skill could help us exam our behavior or decision, and this method is the secret of success Therefore, to learn the skill of introspection is important to success
