The leader sees leadership as responsibility rather than as rank and privilege.
Do not measure your life by your goals but what you are doing to achieve them.
It's amazing how many things busy people are doing that never will be missed.
Plans are worthless, but planning is invaluable.
Listening (the first competence of leadership) is not a skill, it is a discipline. All you have to do is keep your mouth shut.
The only skill that will be important in the 21st century is the skill of learning new skills.Everythi ng else will become obsolete over time.
