Hindsight and Seeing other's mistakes

Why is it that hindsight is 20/20? And you can see everyone elses problems? That is just a fact of life that our vision is far sighted. The future is clouded so we can't see into the future. But once we are past a situation, we can see it clearly. Other people we can see clearly. Sometimes they do get too close to us, and our vision is blurred. But we never see ourselves truely. There are probably some exceptions to this rule. But those who claim that should examine what others percieve of you and see if it translates to what you see yourself. If it does than you are an exception, otherwise you are fooling yourself into believing you know yourself. You only know what you want about yourself and see only the perception of that which you desire of oneself. "If your image translates" doesn't mean that it is the exact same it means that certain points are the same and everything else is similiar. Everyone has a palette of colors to paint the world as they see it. Tradegy usually darkens the colors, while happy things brighten the colors. They may use certain shades at work and a complete different shade at home. This is all determined by what you experience. No one can tell you how to paint your world, you have to color it yourself. Your life is unwritten until you live it. People can play large roles and small roles. From the outside you may feel you are a small part of someones life but until you are out of it completely and the person feels the void the impact is unknown. You may play a pivotal moment in someones life that you meet once. Until you die, and the final score is tallied and the true highlights of your life are played, you will have no clue. Because hopefully their is a massive record out there with everything you have ever down and the impact it has had on the other people in the action. So that it can all be reviewed in the end and say"Yes this person thought he was a somewhat bad person but all these actions say differently." This strays off topic and is somewhat conterdicts the first few statements but it is true and important. No matter how well you can see or not see doesn't matter if you don't know what you are looking for. Also to
change senses, if you hear but you don't listen what is the point of hearing it. To explain if you know someone is speaking to you but you don't listen and actually know what the words are and mean. Then what is the point of hearing them.
