Roselinde Torres in this TED Talk explains how she studied traditional leadership development programs in 4000 companies and found them lacking.

Instead, leaders should address three questions:

#1. Where are you looking to anticipate the next change to your business model and your life?
Figure that out and follow it.

#2. What is the diversity measure of your personal and stakeholder networks?
You need to develop relationships with people who are very different with you.

#3. Are you courageous enough to abandon a practice that has made you successful in the past?
Great leaders dare to be different.

These answers will determine your effectiveness as a 21st century leader in preparing for today and tomorrow.
