i totally agree on the part about accepting and working with emotions contrary to denying them. Self-awareness is the basis of emotional intelligence and you can't improve if you don't know what you are. But why the should you desire negative emotions??? Unless you neural pathways are habitualy used to negative emotions and one is addicted to them or you upbringing taught you what to expect (e.g people treating you unfairly), this desire does not make sense. We are biological machines designed to like stuff that is good for us and to dislike things that threaten us.
