I never thought it was that important or that difficult and there are plenty of people (not you) who are easily smart enough to do it and probably do it very well but will never take even the first step toward advancing their careers. Why they opt to duck and dodge opportunities for better positions and better paychecks is a mystery to me. I mean, I understand the appeal of sitting in the peanut gallery with no sense of responsibility and making snarky remarks about people who stepped up and took on more, but it seems like it would quickly get old and it doesn't pay well.
To each his own.
