Often I speculate that it can be very difficult to be truly great at something and walk in balance. It takes tremendous work, drive and singleness of purpose for even the most talented and gifted to fully actualize those gifts to the point of 'greatness.' It can become something of an obsession so that the individual's global functioning or sense of self apart from the gift and the obsession can become really distorted. One loses perperspective on ones place in the universe, so to speak.

I don't imply that this is always, even mostly true, but I think it is often true.
