One thing I've learned in my career is that you don't have to answer people right away. I've learned how to say, "Can I get back to you about that?" Now I've given myself time to really assess what you asked me to do or what the situation is, think about it, then come up with a plan. Then by doing that, when I come back to you, it's not what I say it's how I say it.
We've got great flexibility and a certain discipline in terms of not doing some foolish thing just to be active - discipline in avoiding just doing any damn thing just because you can't stand inactivity.
