Every person has different capabilities and willingness. To generate the greatest productivity, each person ought to be in the place where they can make the greatest positive contribution. Whoever is willing and able to do what is difficult should delegate anything that isn’t to others who are not.
Often, work with others entails unpredictably long times while you wait for them to respond or complete a dependent task. Your prioritized to do list will enable you to keep making progress in other tasks while awaiting those dependent on others. When you are waiting on other people, you will move on with the next item in the priority queue, following up with the person as a separate task, and while being ready to interrupt whatever you move onto as appropriate in the event they get back to you.
