Leadership is an achievement of trust.
Objectives are not commands; they are commitments.
The best way to predict the future is to create it.
The better a man is, the more mistakes he will make, for the more new things he will try. I would never promote to a top-level job a man who was not making mistakes...otherwise he is sure to be mediocre.
If you want to improve how you manage time - stop doing what doesn't need to be done!
Making good decisions is a crucial skill at every level.
