"Answer the question: 'What would be impossible for you to do, but if you could do it, would greatly increase your productivity, results and/or success?' After you answer it with: 'It would be impossible for me to _______________, but if I could, it would increase my success by doing _________________.' Follow this with: 'Some of the ways I could make this possible are ______________.' Try this. It will help you by pass your own, 'Yes, but' tendencies."
