In preparation for my first marathon, I spoke to a legendary American marathoner, who offered one piece of advice: "Make sure you have three goals: An A Goal, a B Goal, and a C Goal." Soon after the race, I realized that the core principle behind the system applied well-beyond running.

For any arena of life, you can create an A Goal, B Goal, and C Goal. On days when you feel great, you hit your A Goal. On days when you feel ok (most days!), you hit your B Goal. On days when you feel bad, you hit your C Goal.

The ABC Goal System removes any intimidation or guilt: As long as you hit your C Goal, you're making forward progress.
