A complex yet simple thought

When simplicity in life is an aim of a lot, it can get complex when one is lost in thoughts. Some times the more you seek freedom the more you get trapped and the more you think the worst it gets. We would all like to feel happiness and sens of relief but we don't let things be when we actually achieve that. So I ask what are we ? and what do we want ? And fear that the answer would changes as soon as its put in words.
