How often to you or your players use the words or phrases,
“We’ll know when we get there”
All of those wishy-washy phrases really mean “probably not,” or some version of: “if I fail, it’s because I really never said I could/would”.
Pay attention to how often you say or hear language like that and see if you can move these out of your world. I bet that the simple act of paying attention makes you more decisive.
And, I bet you’ll find greater efficiency and lower anxiety along the way.
