Mike Tyson
“Courage doesn't always roar. Sometimes courage is the quiet voice at the end of the day saying, "I will try again tomorrow.”

Roy Baumeister
“Each day, and the living of it, has to be a conscious creation in which discipline and order are relieved with some play and pure foolishness.”
Mary Sarton
“The year becomes new, the day becomes holy, when you sanctify it by spiritual discipline, not otherwise.”
