It has helped me to live with the model that the probability of there being any sort of objective morality or ethics is close to zero, and that a hierarchy of influence within any given context is generally unavoidable. Once you accept this model, you spend less time moralising and angering yourself over perceived wrongs, and can now spend more time on figuring out how to live a happier life despite the fact that there are no set rules.
