I found our Mindfulness and Relaxation lab very helpful because I have never taken the time to seriously give relaxation techniques or mindfulness a try. My one and only exposure to Mindfulness exercises from a Positive Psychology class had been a memorable one. I have never thought of myself as being patient enough to sit still and focus on something as subtle as my own breath. But since then, I have not tried it again. It was great to experience how relaxation techniques (both passive and progressive!) can feel and compare it to mindfulness exercises.
