I am remembering a cross country ski clinic I participated in more than a few years back and a subsequent critique of my style and form. I can still hear the instructor's words as she said, "There are many things wrong here; we can only work on one."
Your to do list is doing you in. Could it be planning, staffing, competence? Delegation, leadership or organizational growth?" In reality, it is probably a combination of many different things.
The pressure is on so what do you do? You work on you. You gather, prioritize and connect. You lay your cards on the table and you renegotiate expectations.
Thinking of sliding into the corner, under the desk, or behind the door? Don't do it. Not only is that not productive, there simply is not enough time.
