“Believe while others are doubting;
Plan while others are playing;
Study while others are sleeping;
Decide while others are delaying;
Prepare while others are daydreaming;
Begin while others are procrastinating;
Work while others are wishing;
Save while others are wasting;
Listen while others are talking;
Smile while others are frowning;
Commend while others are criticizing;
Persist while others are quitting.”
~ William Arthur Ward
