The first discipline is to focus your nest effort on the one or two goals that will make all the difference, instead of giving mediocre effort to dozens of goals. Execution starts with focus. Without it, the other three disciplines won’t be able to help you.

Focusing on the wildly important means narrowing the number of goals you are attempting to accomplish beyond the day-to-day demands of your whirlwind.

Discipline 1 is about applying more energy against fewer goals because, when it comes to setting goals, the law of diminishing returns is as real as the law of gravity.
