Weakness is worse than cancer, I think. It's a kind of psychological or spiritual cancer. And if you have a goal in your life, you'll get psychological immunity. Psychological immunity is a kind of optimism, just like spring.
If there's one thing I've learned, it's this: We all want everything to be okay. We don't even wish so much for fantastic or marvelous or outstanding. We will happily settle for okay, because most of the time, okay is enough.
