The jobs only you can do
One of the milestones every entrepreneur passes is when she stops thinking of people she hires as expensive ("I could do that job for free") and starts thinking of them as cheap ("This frees me up to do something more profitable.")
When you get rid of every job you do that could be done by someone else, something needs to fill your time. And what you discover is that you're imagining growth, building partnerships, rethinking the enterprise (working on your business instead of in it, as the emyth guys would say). Right now, you don't even see those jobs, because you're busy doing things that feel efficient instead.
