My motto (but not easy to adopt)

(I do not know its origin, but Dr. Haruhisa Wago, Saitama Med Univ. introduced me.)

Be a leader, not a boss.

A boss knows everything.
A learder admits mistakes.
　
A boss tells people what must be done.
A leader shows how to do things.
　
A boss criticises.
A leader gives advices.
　
A boss talks first.
A leader listens first.
　
A boss gives orders.
A leader gives directions.
　
A boss demands respect.
A leader earns and deserves respect.
　
A boss rules with law.
A leader shows human-kindness.
　
So, be a leader, not a boss.
