I would call that insanity.
I have this theory of mine since spending time in drug circles. The drug users spend time as well chasing "perfect, permanent and unqualified happiness". And with substances you can achieve the unqualified part. The perfect and permanent parts not really since tolerance comes into play.
Anyway, my theory is that unhappiness is absolutely necessary. Happiness means you are content with what is. And you take action when you want to change to what could be, what you want. But if you are already happy then you don't want to change anything, so you don't do anything even if you absolutely should.
There are a lot of things that tend to prove that unhappiness and its companion - the pursuit of happiness - are the most important motivators. Negative news, commercials, propaganda, populist discourse and so on.
