Trying not to be too much a curmudgeon here, but this article sucks. It claims that being “authentic” means doing exactly what you want at all times regardless of its impact on others. You can be both authentic and considerate/pro-social.

Having said that, I agree that some elements of our personalities might be best left at home. Although I can’t really think of a good example. Unfortunately the best advice tends to be “use good judgement,” which isn’t prescriptive and isn’t helpful during a conflict.
