“Jerry Weinberg, “Secrets of Consulting”: You probably won’t be able to make any changes.

Reading this allowed me to let go of the idea that I was going to make any changes. And this ironically allowed me to see what was going on, and so I may have produced some small effect in the end. It may have simply been a change in perspective from “I’m the high-paid consultant who has been brought in to fix everything” to “I’m probably not going to be able to do anything here, so I’m open to anything where I might be able to make a difference.”
