In real life, if you only hang around the folks with same interests, views, idealism ... it usually means that you just like to feed your ego with daily dose of confirmations for your paradigm. Your addiction to constant influx of cheap confidence, maintaining heroine like consolations inevitably leaves you in sweet dull oblivion of reality.
