Who is this guy and why are we listening to his advice? Edit to add: None of this advice really holds. At the end of the day, your technical ability is what matters. If you're gunning for a promotion, figure out what your manager needs to achieve their annual performance bonus, and make sure you are instrumental in helping them achieve that. Otherwise, find a staff level position elsewhere, and apply for that. Soft skills aren't what holds engineers back from advancing.
