"It's about performance. I like to write first thing in the morning a good long stretch, usually six hours. Sitting in front of the computer was seriously draining - I lost the will to live by noon. My workouts were agonizing. I had nothing left at the end of the day. The Q-Link is remarkable. I started wearing the pendant about 3 years ago. I can now write for 6 hours, workout with intensity and focus, and still have enough energy left to enjoy whatever the evening may bring. I have never been more productive."
