Unconscious Motives

According to some psychologists, a considerable part of human behavior is stimulated and driven by unconscious motives. Maslow states that psychoanalysis has often revealed that there does not need to be any direct connection at all between a conscious desire and the eventual unconscious aim underlying it. For example, a person can be accident prone because of his/her unconscious desire to injure himself/herself and not because he/she is unaware of safety. It is interesting because it is difficult to interpret human behavior because the person could be doing something because of conscious or unconscious motives, but it also makes it more interesting. I believe that there is a reason for everything people do. It could be because of something they learned from their parents or because of an experience they had. Whenever I catch myself doing something I always question it. Sometimes people do not know why they do things and it could be because they repressed something that happened to them or something else.
There are so many different theories about the unconscious mind, but why can't we deal with those things in our unconscious in our conscious? Why is it that we have to stay unaware of them? I know that there are motives that we do not want to have in our minds, but I think we should be aware of them. It is our choice whether or not to act on them. Maybe humans just aren't designed to cope with things they do not understand. I think a person should be aware of their desires and motives,even if they are scary. Unconscious motives are sometimes a mystery, but I think there is always a reason behind them.
