I'm reading one of those throwaway books on the lessons of successful leadership. It's actually quite a hefty tome, so to throw it away with any force could cause some damage to an innocent bystander. Bizarrely enough, that statement would aptly describe my opinions of the lessons it contains - likely to cause harm to others.
I only have only one lesson on leadership that is worth repeating and it's not even mine.
"A leader is best when people barely know he exists, when his work is done, his aim fulfilled, they will say: we did it ourselves."
