In rivers, the water that you touch is the last of what has passed and the first of that which comes; so with present time.
Author: Leonardo da Vinci
Nothing strengthens authority so much as silence.
He who is fixed to a star does not change his mind.
I have been impressed with the urgency of doing. Knowing is not enough; we must apply. Being willing is not enough; we must do.
All our knowledge has its origins in our perceptions.
Men of lofty genius when they are doing the least work are most active.
Who sows virtue reaps honour.
Time stays long enough for anyone who will use it.
Iron rusts from disuse; water loses its purity from stagnation… even so does inaction sap the vigour of the mind.
