No. 3: Failing to self promote – Bragging is one thing, but letting colleagues throughout your industry know of your success through case studies, promotion bulletins or other such tools is quite another. Losers often fail to recognize the importance of letting others know about their successes, or go about it in entirely the wrong way.

No. 2: Confusing efficiency with effectiveness – Those who think that communicating via e-mail replaces the need to actually talk with people around them fail to recognize the importance of personally connecting with others in today’s highly automated and technological environment. Communicating in person, or at least via phone, whenever possible is imperative for success-seekers.

No. 1: Believing that you are irreplaceable – There is no room for “divas” in the workplace. As soon as you convince yourself that you and only you can do the job “right,” your star will surely start to fall.
