Discipline is doing what you really don’t want to do so that you can do what you really wanted to do.
During the 14th century in what is now Belgium, there lived a man named Reynald III. Reynald was a nobleman, the rightful duke over his ancestral lands, but his brother revolted against him and unsurped him. Reynald’s brother needed duke out of the way, but he didn’t want to kill him. So he came up with an ingenious plan.
Because Reynald was a very large man, his brother had him put int a room with a smaller than average door. If Reynald would simply lose some weight he would be allowed to leave. In fact, the usurping brother promised that if Reynald left the room, his freedom and his title would be restored.
But Reynald was not a man of discipline, and his brother knew that. Everyday the brother had trays of delicious foods delivered to his brother’s room. And Reynald ate. In fact instead of growing thinner, he grew fatter and fatter.
