“Athletes need to enjoy their training. They don't enjoy going down to the track with a coach making them do repetitions until they're exhausted. From enjoyment comes the will to win.”

“Encourage kids to enjoy running and play in athletics. Don't force them to run too much competition.”

“No one will burn out doing aerobic running. It is too much anaerobic running, which the American scholastic athletic system tends to put young athletes through, that burns them out.”

“Train, don't strain.”

“It's just a matter of understanding what's necessary and discipline yourself to do it.”

“If you want to be a successful runner, you have to consider everything. It's no good just thinking about endurance and not to develop fine speed.”

“You write not for children but for yourself. And if by good fortune children enjoy what you enjoy, why then you are a writer of children's books.”
