We are all pleasure seekers. There are pleasure centers located in the human brain, which, when activated, are associated with feelings of euphoria. This happens to us every day.
During the day we go through naturally occurring periods when we feel comfortable, secure, happy, and fulfilled and this is followed by periods when more negative feelings are aroused (anxiety, insecurity, discomfort). We humans are highly reinforced by positive feelings of pleasure. We want to experience euphoria again and again.
Fortunately, that’s not all there is to life.
