When you drink the water, remember the spring.
Cherish your own emotions and never undervalue them.
When you make a mistake, don't look back at it long. Take the reason of the thing into your mind and then look forward. Mistakes are lessons of wisdom. The past cannot be changed. The future is yet in your power.
The most silent people are generally those who think most highly of themselves.
Opinions are the cheapest commodities in the world.
Adapt or perish, now as ever, is nature's inexorable imperative.
We must make the world honest before we can honestly say to our children that honesty is the best policy.
Impossible is a word only to be found in the dictionary of fools.
We teach people how to remember, we never teach them how to grow.
In peace, there's nothing so becomes a man as modest stillness, and humility; but when the blast of war blows in our ears, then imitate the action of the tiger, stiffen the sinews, summon up the blood...now set the teeth and stretch the nostril wide, hold hard the breath, and bend up every spirit to its full height!
