I've not seen this full cycle since late adolescence, and as Adelene mentioned sometimes the cycle short circuits. The short circuit for me usually occurs when I find the proto-idol empirically wrong on a thing or two, and we are all empirically wrong on a thing our two some of the time. Humanity is then re-endowed upon the proto-idol and I go on my way. Probably still admiring of the idol in some aspects, but not fully entranced and in a glamor anymore. He/she/it is human too.
We all have heroes or idols, people we look up to and turn to, in one form or another, for guidance or wisdom. Over the years, I've noticed that my feelings towards those I've idolized tend to follow a predictable pattern. The following is the extraction of this pattern.
