"When the spirits are low, when the day appears dark, when work becomes monotonous, when hope hardly seems worth having, just mount a bicycle and go out for a spin down the road, without thought on anything but the ride you are taking."
"Every time I see an adult on a bicycle I no longer despair for the future of the human race."
