Today,i came across this book on leadership. One section calls the difference between a boss and a leader. Let me share with you.
BOSS VS LEADER

The boss drives subordinates;
the leader coaches them.

The boss depends on authority;
the leader on goodwill.

The boss says "I";
the leader says "We".

The boss fixes the blame for the breakdown;
the leader fixes the breakdown.

The boss knows how it is done;
the leader shows how.
