“Whoso neglects learning in his youth, loses the past and is dead for the future.”

“To quarrel over the past is to lose the future.”

“Whoso obedience from his subjects seeks,
'Tis fitting that he first should learn to rule.”

“Futures not achieved are only branches of the past: dead branches.”

“He that in his Studies wholly applies himself to Labour and Exercise, and neglects Meditation, loses his time: And he that only applies himself to Meditation, and neglects Labour and Exercise, does only wander and lose himself.”

“Some of the best lessons we ever learn are learned from past mistakes. The error of the past is the wisdom and success of the future.”

“He who spends time regretting the past loses the present and risks the future.”

“The past has lost, as it always loses; the future has won, as it always wins.”

“It was never too late to learn something. The past is unalterable in any event. The future is the only thing we can change. Learning the lessons of the past is the only way to shape the present and the future.”

“Trust no future, howe'er pleasant!
Let the dead Past bury its dead!
Act, act in the living present!
Heart within, and God o'erhead!”
