Do You Have a Task Overload?

In your book, you talk about the concept of task overload. You describe landing a fighter jet on an aircraft carrier at night as 'the hardest thing to do in all of aviation' And so for those of us who are not fighter pilots, how can we deal with that? How does one focus and stay focused during such a stressful situation? Are there any tips I could give my fellow airmen or even non-pilots from our own lives?
