Not all that much, really. I'm mostly satisfied with the decisions I made up until my 3rd year of college or so. And given that a lot of the problems that began then were related to a relationship, I'm not sure that there was anything I could have known that would have made a difference.wait, seriously? he had relationship problems and can't think of any possible advice that would have headed them off? in other words, he cannot conceive of any advice that would have persuaded him not to get into the relationship. but, he also cannot conceive of any advice that would have made the relationship turn out more pleasant. he takes it for granted that the best life both 1) has romantic relationships that hurt people and 2) cannot be improved or made safer with knowledge, skill, or good ideas.
