A wise man gets more use from his enemies than a fool from his friends. - Baltasar Gracián

Do not enter where too much is anticipated. It is the misfortune of the over-celebrated that they cannot measure up to excessive expectations. The actual can never attain the imagined: for to think perfection is easy, but to embody it is most difficult. The imagination weds the wish, and together they always conjure up more than reality can furnish. For however great may be a person's virtues, the will never measure up to what was imagined. When people see themselves cheated in their extravagant anticipations, they turn more quickly to disparagement than to praise. Hope is a great falsifier of the truth; the the intelligence put her right by seeing to it that the fruit is superior to its appetite. You will make a better exit when the actual transcends the imagined, and is more than was expected.

Say farewell to luck when winning. It is the way of the gamblers of reputation. Quite as important as a gallant advance is a well-planned retreat. Lock up your winnings when they are enough, or when great. Continuous luck is always suspect; more secure is that which changes. Though half bitter and half sweet, it is more satisfying to the taste. The more luck pyramids, the greater the danger of slip and collapse. For luck always compensates her intensity by her brevity. Fortune wearies of carrying anyone long upon her shoulders.

We have eyelids but not earlids, for the ears are the portals of learning, and Nature wanted to keep them wide open.
