The significance of learning life lessons cannot be understated. It is an experience that if you do not realize from the lessons that life is trying to teach you, then they will be taught to you again and again until you do. A essential cause of much suffering and unhappiness is people's unwillingness to learn from mistakes, either their own or the mistakes of others. History is full of examples of people that kept making the same mistakes because they failed to realize from the lessons that life was teaching them. There are two main reasons for why this happens over and over again, ego and fear. Extreme pride and haughtiness caused by an out of control ego has been the downfall of many immense people. The strong sense of self confidence and obstinate determination gained from having a big ego can certainly help in life, but it is the negatives that will inevitably grounds self devastation. You must always keep an open mind so you can see all sides of an issue. Some of the hardest and best life lessons are learned when you are thoroughly persuaded about something but then see it in a different light and change your mind. The most frequent cause that people do not realize from life lessons is fear. This is because applying what you realize from life lessons is really about alteration, and alteration scares the hell out of people. They are so afraid of leaving the familiar that as each new opportunity presents itself they let it pass by, no matter how much it would improve their life. People become so wrapped up in their personalities and who they think they are; they think that change is impossible. "That's just who I am", is what you will hear often. This is said out of fear, because the person who said it does not want things to change. They want the whole thing to stay the same because it is at ease and known. The truth of the matter is that change is the only constant in life. That is why being flexible and having the aptitude to roll with the punches are such important life skills to have. Realize from the different lessons in your life, and for sure, you will grow from it.
