Perfection is the enemy of progress.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
Whenever an individual or a business decides that success has been attained, progress stops.
Progress is impossible without change, and those who cannot change their minds cannot change anything.
The reasonable man adapts himself to the world: the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
Without deviation from the norm, progress is not possible.
