I sure have.
On some days we feel invigorated and activated; on other days we have little desire to do anything. For many parents, getting our children to practice the piano or finish their homework is a dreaded nightly chore of grumblings and drooping shoulders.
As a leader, I am so inspired when the people around me are highly motivated. Providing leadership for these individuals is like sailing a ship in the open sea or flying a kite on a windy day. Trying to lead people with low motivation is like rowing the Titanic with a spoon.
