The work not yet done

Could be...

That you don't know what needs to be done.

That you don't know how to do what needs to be done.

That you're afraid to do what needs to be done.

It's frustrating. We want to move up, we want our project to make more of an impact, we want to ship--but the undone work hangs over us. 

If you care enough, the path forward is clear, isn't it?

You can model what needs to be done, basing your next steps on what others have done before you. You can ask your boss or your clients for an agenda. You can test and test again. You can leap.

You can learn how to do what you don't know how to do. You can improve your skills, get better tools and do the hard work of actually getting better at the work.

But most of all, you can realize that the most urgent work is the work of dancing with our fear, because the fear is the real reason the work isn't getting done.
