Stop Doing "the thing"!

There's a "thing" that you are good at, likely better at than anyone else in your agency, and the more you do that "thing" the more you are holding back the growth of your agency.  Your job is no longer "doing the thing" -- as the leader of your growing agency your job is to build the system in which "the thing" gets done.  If you have to do it, your growth is stalled!
