By three methods we may learn wisdom: First, by reflection, which is noblest; Second, by imitation, which is easiest; and third by experience, which is the bitterest.

There are three methods to gaining wisdom. The first is reflection, which is the highest. The second is limitation, which is the easiest. The third is experience, which is the bitterest.

Think no vice so small that you may commit it, and no virtue so small that you may over look it.

The superior man is firm in the right way, and not merely firm.

The easiest and noblest way is not to be disabling to others but to be improving yourselves.

If they fool me once, it's first time. If they fool me again, I am learning. If they fool me third time, then I am a fool.
