You'll have to do a bit of selling today: either for yourself or for a project you want other people to pitch in on. If all you do is focus on what you want out of them, folks may find you a bit insensitive. But if you focus on what's in it for them, you can get their attention and get them on board! Put yourself in their position and think how they would think. Keep communication simple and straightforward, and there's a higher chance you will communicate yourself in a positive way.
