We often think of urgent and important as synonymous. They're not. The opposite is true: being a slave to urgency is a sure path to mediocrity.
When we ask ourselves "What is important?" the answer is rarely time sensitive. Rather, it has a ring of truth to it, and requires the work of carving out time from our urgent days.
When we take this a step farther, we find that the most important things in life have zero urgency to them: time with family, taking care of ourselves, investing in our future, etc.

The most important skill is cutting away the urgent to get to what is important.
