“One of the things psychologists used to say was that if you are depressed, anxious or angry, you couldn't be happy. Those were at opposite ends of a continuum. I believe that you can be suffering or have a mental illness and be happy - just not in the same moment that you're sad.”

“One of my signature strengths is the love of learning, and by teaching, I have built it into the fabric of my life. I try to do some of it every day.”
