There is no shortage of mechanisms by which to measure almost anything.

No idea will work if people don't trust your intentions toward them.

It remains true that great managers recognize individualities and focus on developing strengths rather than weaknesses. Great leaders, in sharp contrast, recognize what is (or could be) shared in common - a vision, a dream, a mission, whatever - and inspire others to join them in the given enterprise.

Authenticity is your most precious commodity as a leader.

In the minds of great managers, consistent poor performance is not primarily a matter of weakness, stupidity, disobedience, or disrespect. It is a matter of miscasting.

Don't waste time trying to put in what was left out. Try to draw out what was left in.

Remember, what you focus on expands; results follow focus.
