Plan. Write things down. Be precise but use as few words as possible. It should be clear from reading your few tiny bullet points you know exactly what you are about to accomplish in an aggressive manner. Secondly, know your liabilities. Specify these in your plan as a separate set of bullet points. Finally give the plan to your boss. When you have completed your task according to the plan the boss will have less room to complain. Ask your boss where they identify complexity. Refactor early to eliminate effort later.
