What's an insight? 

The technical definition is to gain an accurate and deep understanding.

The application you’ll know is the solution that comes to mind when you’re not thinking about the problem at all.  Maybe you’re on a walk, doing the dishes, or on a long drive.

How do you experience more?

Think back to your own life, when do you have your best ideas?  Pay attention over the next few days and record the activity, location, and environment when this came to mind.

How can you make a positive impact?

Take your next step while you have the energy from the insight.  This could be writing it down, scheduling time later, or taking the next step immediately.
