Some things are urgent; some things are important: very few things are both urgent and important.

The Thinking Behind The Tweet

The vast majority of important things are not urgent and so they can be postponed. And, quite a bit of the time, that's exactly what we do.

When important things are postpones their true priority can be obscured and forgotten. And, quite a bit of the time, that's exactly what happens.

• Napoleon Hill taught "Plan the Work and Work the Plan". 
• Stephen R. Covey taught the way to sort out tasks/timing into Importance/Urgency quadrants.
• Pareto taught the "80/20 Rule". 

With these three tools, we have what we need.

Now, it's up to us to use them.
