Well, that's a conundrum.

Say you get this opportunity to do something you've always wanted to do. Something that you know you would be grrreat at. Something that is a culmination of all your prior work - professional and volunteer- for the past 10 years. But to take that opportunity would mean giving up something you love very much and have started to get attached to. It would mean sacrificing a big thing to get something even bigger down the road. What would you do?
