This advice is curious to me. How do you derive this from your beliefs? I can understand you saying "don't be a dick just to be a dick", because that would cause pointless suffering. But if I can advance my own wealth or happiness by being a dick in such a way that I can reasonably avoid retribution, why shouldn't I?
