Reality-Based Decision Making at www.jeff-hester.com.

Some of what you know is fine, but some isn't. Here's the rub.
You don't know which is which. More often than not your
fate hangs on that simple fact.

Since leaving ASU I am speaking, advising, and coaching, sharing my
experience and perspective with companies, organizations and
individuals facing high-stakes decisions in today's rapidly changing world.
