I was recently listening Darren Hardy's Compound Effect CD in my car, when he used a great line that really struck a cord in me as a better way to say something.
Most managers/interviewers use the phrase 'what are your strengths and what are your weaknesses?'. Now, the word 'weaknesses' conjures up negative thoughts within and sows a seed of uncertainty and lack of competance. Therefore a better phrase to use would be 'what are your strengths and what do you need to improve?'
Just by taking out a negative word and replacing it with something more 'thought provoking' works wonders when trying to get a great answer, as opposed a knee-jerk reaction based on protecting ones self esteem.
Pick your words wisely and I guarantee you'll get greater results in all areas of your life.
