„Whatever we do must be in accord with human nature. We cannot drive people; we must direct their development… The general policy of the past has been to drive, but the era of force must give way to that of knowledge, and the policy of the future will be to teach and to lead, to the advantage of all concerned“
— Henry Gantt
