Bzzzzt. What you typed next showed absolutely no evidence of any thinking at all, much less further thinking.
As an atheist, I believe in clinical and applied psychology, both of which offer PLENTY of self-help tools. I just took an entire MBA class on managing interpersonal relationships which could basically be boiled down to a study of the empirical evidence that following the Golden Rule makes you a more effective leader or teammate. Jesus espoused the golden rule, but he wasn't the first and the fact is that the rule works (as shown by statistically significant, tangible, real-world effects), whether or not one (or anyone) believes in an invisible sky being, so science leads us to the conclusion that we should be nice to each other completely independently from religion or Christianity.
