Consider the idea that charisma can be as much a liability as an asset. Your strength of personality can sow the seeds of problems, when people filter the brutal facts from you.

In a world of constant change, the fundamentals are more important than ever.

If you have a charismatic cause you don't need to be a charismatic leader.

You can't manufacture passion or "motivate" people to feel passionate. You can only discover what ignites your passion and the passions of those around you.

Resilency, not perfection, is the signature of greatness.

Be rigorous about your HR decisions. There is a difference between rigorous and ruthless.

Building a visionary company requires one percent vision and 99 percent alignment.
