She’s the one with the can-do attitude. The boss needs that proposal by tomorrow? No problem. Have a 3 a.m. conference call? She’ll be there. You need 10,000 copies correlated and stapled? She can do that, too. Sure, she may over commit, but you don’t get ahead by saying “no.”

On the climb up the corporate ladder, the line between strength and weakness isn’t always clear. Although her eagerness to please served the over-committer early in her career, now, she has an overflowing calendar and a reputation as the boss’s pet.
