I believe psychology has done very well in working out how to understand and treat disease. But I think that is literally half-baked. If all you do is work to fix problems, to alleviate suffering, then by definition you are working to get people to zero, to neutral.

I believe in hard work. I think that everything flows out of that.

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.

I think I get angry when people cause serious suffering or don't alleviate suffering when they could.

Positive thinking is the notion that if you think good thoughts, things will work out well. Optimism is the feeling of thinking things will be well and be hopeful.

I don't know if I believe in luck. I think I'm very fortunate.
