A great deal of people here say, and I'm sure do, they put themselves up to a higher standard. This includes INTP's for the most part, when we aren't apathetic. However, it isn't hard creating the standard, it's hard trusting that this standard is the best way to live, or right. I think this leads to some of the neurosis that exists. An INTP has the potiental to obsess over their personal standard because it doesn't necessarily line up with the overall external standard, and even though this is the furthest away from an INTP's mind if you add failure to this-- i.e. their personal standard failed-- the doubt makes you change the standard and blend in. Once you do this perhaps you do get more success; if you get more success then their is a chance that you take that as 'you aren't smart/good/whatever enough to create or analyze your own values', extremely pessimistic, but if this occurs several times I can understand I know what it's like to be a neurotic mess. Looking at the cup half-full is a challenge at times when you feel (whether you are or not) strange.
