Do not blame anybody for your mistakes and failures.

The maxim urges radical personal accountability: errors and setbacks are best met by owning one’s part in them rather than shifting responsibility to colleagues, circumstances, or “bad luck.” In Baruch’s world of finance and public service—domains where decisions have consequences and excuses are plentiful—the advice functions as a discipline of character: accepting blame clarifies what can be learned and changed, while blaming others preserves ego at the cost of insight. The quote also implies a pragmatic ethic: responsibility is a precondition for improvement, because only what you acknowledge as yours can be corrected.
