There is a whole range of responses you can get when asking another for a commitment. I am not speaking about what they say, I am speaking about the mood in which the commitment is delivered, but you have to listen for that.
Moods and Attitudes can vary from very low on the scale as in annoyance or obligation, or lower, all the way up to challenge, adventure, and empowerment.
To have powerful commitments that you can count on, you need to listen for what’s driving that promise behind the words you want to hear. The most powerful commitments are when there is no gap between the speaker, the speaker’s promise, and their actions. Their experience is one of “I am that I will…”, and you know they will do everything in their power to fulfill that.
