Doing the work entails first determining what the work is.
I am not always great at this—I tend to underestimate (sometimes badly) how much it’s going to take to get something done. Case in point: the brand-new workshop I agreed to design, thinking, “That will take, what, four hours?”
Two weeks later, the workshop unfinished and the hours worked mounting, I wonder how I could have been so wrong.
What is the work? What tools do you need? What assets do you already have? Who else needs to do the work with you? Who can you ask for insight into what you may be forgetting?
