I think that this is a function of a lot of things that change over time. I am/was heavily influenced by my parents opinion of me. I used to think that if my mother repeatedly says that I am not good enough to exist, then maybe that's the truth. As, if I am truly that bad then how could I possible know? That would be a really silly recursion. If I was crazy how could I tell whether or not I was crazy? Surely, some other reference was needed.

I know that this sounds silly, but this is an improvement.

For the life of me I can't think about a pattern that follows specific types of opinions. It's just the nature of this chaotic world. There is an infinitely large range of possible permutations of experiences and reactions to those experiences. So, it's quite tough to say if given the same set of circumstances whether or not two people will have the same opinion, or think the same way. Hence, it's tougher to extract a broad pattern surrounding such things. Unless you spend a lot of time with the person and find out the why and how.
