Overview
It's going to become quite obvious today that someone who's been full of great ideas is also full of empty promises. They are doing nothing at all to build on their plans or follow through with what they told you there were going to do, and they show no sign of changing any time soon. Instead of calling them on it or letting yourself get frustrated, just move on. Skip over them and do what you were planning on doing before they came onto the scene. You don't really need them anyway.
