Landing a new job will make you feel great, but it’s just a first step. Once you start, you’ll need to win over your boss, fit in with your co-workers and prove how valuable you are to the company. We asked Florence Littauer, co-author of Personality Plus at Work, how to make the best first impression.

Ask for help. Speak up instead of pretending to know it all. It will give you a chance to interact with colleagues and help avert misunderstandings.

Avoid gossip. Chatting by the water cooler is a good way to make friends, but keep the talk upbeat and nonjudgmental.

Focus on work. It’s fine to have photos of your kids on your desk and to program your babysitter’s cell into your speed dial. But try to save family business for lunchtime so you don’t appear distracted and preoccupied.
