I've always loved this quote. I try to live by it, though I'm not always successful.
I just read Bill Zeller's suicide letter. I never knew him. I wonder if the people that knew him saw him in the same light in which he saw himself. I understand his wish that he could have ended his pain in another way. Some way that wouldn't hurt the people around him so much. I wish he could have gotten help.
In the meantime, I will do my best to "Be kind, for everyone you meet is fighting a hard battle."
