I do get down on myself from time to time for not being able to "keep it together"(I attempted suicide once, and spent some time in a psych ward on 2 occasions).
But, when I consider respected figures both current and historical, it becomes apparent that humans in general have a hard time being consistently rational.
Ghandi, Tolstoy and Mark Twain (he saw himself as curmudgeonly and made poor business decisions) come to mind, as well as numerous successful actors like Robin Williams. I also know of 2 pastors in a nearby town who basically flipped out and made the news.
Anyone else think along these lines?
