On Human behavior

Why do people find it so hard to understand that there is no person that is perfect? We should never think that others are better than us. We should struggle trough the current of life to find our place, but never forget that we are human and that we have feelings and that we should stop every once in a while to cry, and clean our soul, to laugh, and refill our life points, to talk, so we can clear our minds and more importantly to help the ones that are always walking beside you and backing you up.
