Been reading Bill Hybels latest book Axiom. It is a great resource for leaders. Basically includes short chapters with 2 or 3 page thoughts from Bill on a number of leadership areas.
One particular lesson that stands out to me is the principle of "Speed of the Leader, Speed of the Team." As Bill writes, "If you cannot say 'Follow me' to your followers - and mean it - then you've got a problem. A big one." This is a great statement. Leaders must never expect from others anything more than they're willing to deliver themselves. The leader should set the tone.
Speed of the Leader, Speed of the Team. Don't expect your team to give or fight or sacrifice or Love or Forgive or Stay focused more than you are.
Lead by Example.
