the happiest person

Sometimes I believe that foolish people are happier than average people because they seem to live in a different world. They don't notice when other people are manipulating them; for them no-one has ulterior motives, etc. sometimes I really envy this kind of people, since they are unaware of what's happening around them they don't worry too much the way average people do.
In the other hand , I'd like to be wise enough to learn how to avoid this kind of people, both fools and manipulative people
