I work as a copy writer for an ad company and I agree and practice most of these. Since I’m young, (lol) I think the only disagreement I have with this article would be the third point. The idea of being good at only one(or two) things can be limiting. For me, entertainment, hobbies, and other passions, actually helps me adapt in my chosen career. I think being able to explore outside our work adds to a more fulfilling life. Finding balance rather than tunnel visioning. Again, just an opinion.
