It looks like you'll receive an offer you can't refuse this week. Usually, you'd jump at the opportunity except that you're already spoken for. You made a commitment to somebody else and you can't break it – no matter how much you want to. But does that mean you have to watch this big break pass you by? Not necessarily. See what you can do to work out an arrangement that suits everybody. Maybe it's a leave of absence, switching to part-time status, or going freelance for a while? In any case, you'll be able to work out something as long as you're upfront and upbeat.
