Write down the number you came up with in the last task - in big, bold, permanent marker (seriously).

This is your stretch number. This is the number you're going to work toward hitting over the next four months - above all other numbers.

It is the first number you're going to think about when you wake up every morning and the last number you think about before you go to sleep. Write it down, share it with your team, tell your wife or husband, boy / girlfriend, friends, kids, pets, parents.

This is your new mission.
