Advergirl’s Rules for Career Success. Amen on number one:
Never be silent in a meeting. You’re there for a reason. Participate. Add value. Take notes.
Until the last year or so I’ve always been quiet in meetings, mostly because I don’t want to be that person who constantly talks about themselves, over inflates their importance, and worries about things that they have no business worrying about. But your boss wants to know you’re paying attention, that you’re paying attention, and that you can spot problems before they occur.

These are great. I, too, have felt many times that since a problem wasn’t related to my job directly, I should keep quiet because it isn’t my business. I’m learning, though. Great article, thanks for the pointer!
