Don’t let ambition get ahead of opportunity. By fixating on a future job or project, you become impatient with where you are. You don’t tend enough to the responsibilities you do have, and so ambition can become counterproductive. It’s important to know how to find the balance—do the job you have well; be patient; look for opportunities to pitch in and expand and grow; and make yourself one of the people, through attitude and energy and focus, whom your bosses feel they have to turn to when an opportunity arises.
