Sometimes we confuse feeling productive with being productive. 

You might jump into your workday and knock out a bunch of small tasks.

Completing this type of work isn't wrong; it's often necessary. But these are tasks that can often be completed quickly, later in the day.

This gives you time to focus your prime thinking time on the more important decisions.

The more responsibility you have, the more important focus becomes. So, identify your most important decisions for today, and make those your priority.
