This is probably less of a choice and more of a personality defect. It’s ultimately an alienating and soul crushing way to live your life. But there is no way to be successful without being highly critical, at least as an editor. The danger is when you turn it on yourself and people you are close to (inevitable). In a culture where we’re sold blind positivity (profit motive), it's important to stay critical, to stay on your toes. As an editor this is most important. But it’s also important to be an “A-type” thinker instead of a “B-type” thinker: you have to offer ways to improve what it is you’re criticizing, and not just be critical for the sake of criticizing.
