I am blanking on who said this about Robin Williams (maybe Jay Leno?) but after his suicide the famous friend pointed out that Robin fought depression, etc on a daily basis and won except for this one day.
OK, I found the quote. It was Jay Leno: "He fought a lot of battles, and he won 99% of them, but just lost this one."
That quote really resonated with me - if that doesn't sound like a strong person I don't know what a strong person is.
