Executives are doers; they execute.
Concentrate on one task.
“What contributions should the enterprise expect from me over the next 18 months to two years? What results will I commit to? With what deadlines?”
“Is this the course of action ethical? Is it acceptable within the organization? Is it legal? Is it computable with the mission, values, and polices of the organization?”
Your action plan is a statement of intentions.
Create a system for checking results against the expectations.
