“It's an issue for me
I went to see this therapist
She said just do the best you can do
Do the best you can do
I was hoping for something more specific”

Obituaries (1979)

Bishop-elect Walsh's breadth of experience enables him to teach by example https://web.archive.org/web/20040912021719/http://www.cny.org:80/wl090204.htm (September 2004)

Presidential campaign (April 12, 2015 – 2016), Democratic Presidential Debate in Miami (March 9, 2016)
Context: I am not a natural politician, in case you haven’t noticed, like my husband or President Obama. So I have a view that I just have to do the best I can, get the results I can, make a difference in people’s lives, and hope that people see that I’m fighting for them and that I can improve conditions economically and other ways that will benefit them and their families.

Paris Review Interview (1990)
Context: I know when it’s the best I can do. It may not be the best there is. Another writer may do it much better. But I know when it’s the best I can do. I know that one of the great arts that the writer develops is the art of saying, No. No, I’m finished. Bye. And leaving it alone. I will not write it into the ground. I will not write the life out of it. I won’t do that.
