The best way to look at this scenario as Tony Robbins puts it, is to consider the Pareto Law or better known as the 80:20 Rule.

By the way, I remember vividly quality guru Joseph Juran often referred the Pareto's Law as "The Law of The Vital Few and the Trivial Many".

Nonetheless, the Pareto's Law should serve as a daily reminder to focus 80% of our time and energy on the 20% of our work that is really important.

Don't just "work smart", work smart on the right things.
