 We make mistakes that we may be wrong, that a year or 10 years from now we may think, how could we ever have thought that? And when you manage that contradiction, then it somewhat reduces the self-righteousness, the sanctimony, the finger-wagging quality that tends to accompany advocacy. You know, none of those things have ever, sanctimony has never helped convince anybody of anything. I think that actually improves one's advocacy rather than undermines it.
