One of Joseph Brodsky's 6 rules for playing the game of life like a winner, from his magnificent 1988 "Speech at the Stadium" – the greatest commencement address of all time:
At all costs try to avoid granting yourself the status of the victim. Of all the parts of your body, be most vigilant over your index finger, for it is blame-thirsty. A pointed finger is a victim’s logo — the opposite of the V-sign and a synonym for surrender. No matter how abominable your condition may be, try not to blame anything or anybody: history, the state, superiors, race, parents, the phase of the moon, childhood, toilet training, etc. The menu is vast and tedious, and this vastness and tedium alone should be offensive enough to set one’s intelligence against choosing from it. The moment that you place blame somewhere, you undermine your resolve to change anything.
