Stopdog is right. Attorneys as a profession have among the highest rates of depression, substance abuse and suicide.

In reference to having a T be smarter, I also think that is important. I tried out several who were clearly fairly dim and I could not have worked with them. My T seems brilliant as long as we're in his area of expertise. When I explain something he knows nothing about to him (something legal or horse related for instance), he understands quickly and remembers what I tell him.
