Steam becomes a mighty power only when it allows itself to be imprisoned in a strong little reservoir, produces tremendous motion and carries huge weights by permitting itself a tiny and measured outlet.
Far better to think historically, to remember the lessons of the past. Thus, far better to conceive of power as consisting in part of the knowledge of when not to use all the power you have. Far better to be one who knows that if you reserve the power not to use all your power, you will lead others far more successfully and well.
There is no power on earth which can be kept long confined within a narrow limit. It cannot be kept compressed too long to allow of expansion at a subsequent period.
