Some die because they feel everything, others because they feel nothing. Some are fools because they suffer no regrets, and others because they do. - Baltasar Gracián

Know the fortunate in order to choose them, and the unfortunate in order to flee from them. Bad luck is usually brought on by stupidity, and among outcasts nothing is so contagious. Never open the door to the least of evils, for many other, greater ones lurk outside. The trick is to know what cards to get rid of. The least card in the winning hand in front of you is more important than the best card in the losing hand you just laid down. When in doubt, it is good to draw near the wise and the prudent. Sooner or later they will be fortunate.

Do not be held a cheat, even though it is impossible to live today without being one. Let your greatest cunning lie in covering up what looks like cunning.

Many pleasant things are better when they belong to someone else. ... When things belong to others, we enjoy them twice as much, without the risk of losing them, and with the pleasure of novelty.
