The other day Emma, 6, asked me a series of questions to which all of the answers were yes. She stopped and stared at my head for a bit and said "Yeah, ya sure got a lot of yesses in there."
I loved that.
I used to have a lot of "I can't" in there. Saying yes more often has helped me be more clear about the difference between can't, won't, and don't want to. When that all becomes clear, yesses are easier to get to.
