I love this insight! It’s me to a T, and I like that you put words to the feeling—responsibility. I don’t want to say yes and then have to attend some thing or do some thing when I don’t feel like it. Like you I am great with spontaneity. Call me on Tuesday afternoon and say do you want to run out for lunch do you want to go to dinner and chances are I’ll say yes. Ask me to put the same lunch or dinner on my calendar for the following Tuesday and I’m likely to say no. Why? I don’t know what mood I’ll be in next Tuesday. Great job on defining this; it’s pretty simple.— responsibility.
