About the only problem with success is that it does not teach you how to deal with failure.
I think IT projects are about supporting social systems - about communications between people and machines. They tend to fail due to cultural issues.
I think in terms of family, in terms of relationships, in terms of work, competition to be the favorite, to be the noticed, to be the one - I don't know if it exists for all personalities, but I know for sure it did with me.
