I came across the quote from Yogi Bahajan in a new book I got yesterday

"Count your merits: You always count your defects and never your merits. Count your merits and leave off the deficiencies - they were meant to be filled with your efficiency. That's all it takes. When you don't give in to your deficiency, it is efficiency. You're not a sinner... Just deficient. Keep up and you'll be efficient. That's all it takes and it will carry you through - that's the secret of life. NO BODY'S PERFECT!
