It's time to quote (once again) Joseph Brodsky:

"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."
