pull your weight

I love competition and over the years have played on a lot of sports teams. I have been the best player on the team and also the worst player on teams. My goal though, was to be a key contributor to the team. Making the team better has always been my goal. Wherever we work we are on a team. On every team there are those who are out front pulling the team and then there are those in the back being dragged, but most are in the middle. Where do you see yourself? Better yet, where do others see you? Are you someone who not only pulls your own weight but also picks up others slack as well? Or are you the one who everyone has to drag?
