This is in direct conflict with the individual, varied and unique lives we lead. Therefore, any comparison with what is “normal” is comparing like with unlike and inevitably results in disappointment with yourself; this implicit inadequacy and disappointment is the nourishment of all religions and companies.
This is a particular problem for those who fall shorter of “normal” and are deemed disabled. For example, Parkinson’s sufferers can be drawn into comparing themselves to other people (and also to their past selves) and feel the loss imposed by the disease.
However, all notions of what is “normal” are relative and partial. We are free to choose our own “normality” and who we compare ourselves to. Of course, taking on this freedom shackles us with responsibility for the choices we make. Many of us follow, without question, society’s “normality” to avoid such a burden.
