An extract from The Street Lawyer, John Grisham.
How appropriate.

"I've seen everything. You learn to stay level. When a client kicks the habit, finds a job, gets an apartment, you say a little prayer of thanks. But you don't get excited, because another Ruby will come along and break your heart. There are more valleys than mountains.
"How do you keep from being depressed?"
"You draw strength from the clients. They are remarkable people. Most were born without a prayer or a chance, yet they survive. They trip and fall, but they get up and keep trying."
