Optimistic quote

This quotation describe a very common behavior people show in life. If we always see the worse in something , somebody, or a projrct we will never see the good in it, but if we behave contrarily positive things will happen because we make them happen, we work to that. In a relationship, if one patner see the other with pessimistic remarks, he will see his or her weakness , failures he or she makes on a daily basis and think that the relationship will never go on. However a person with good beliefs who is kind, who is looking for the goodness, the profit, will end up with it. A patner who behaves like this will find out the most interesting part of the other ,since everyone has one no matter what the evil they did.
I think optimism is the best state of mind we should have ;although, it is the more difficult. It direct our actions, life and happiness. Only knows that everything is possible in this world if we believe; even if we don't get the appropriate result, it is worth trying.
