Barbra Streisand

To have ego means to believe in your own strength. And to also be open to other people's views. It is to be open, not closed. So, yes, my ego is big, but it's also very small in some areas. My ego is responsible for my doing what I do - bad or good.

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.
