If you don't take change by the hand, it will take you by the throat.

No compromise with the main purpose; no peace till victory; no pact with unrepentant wrong.

It is wonderful what great strides can be made when there is a resolute purpose behind them.

I will say that he must indeed have a blind soul who cannot see that some great purpose and design is being worked out here below of which we have the honor to be the faithful servants.

To improve is to change; to be perfect is to change often.

The stern compression of circumstances, the twinges of adversity, the spur of slights and taunts in early years, are needed to evoke that ruthless fixity of purpose and tenacious wit without which great actions are seldom accomplished.
