The same day I read this, I also happened to see the verse of the day:
Now, I just so happened to be worrying a bit about an upcoming trip. And I was feeling a bit of self-pity about how much better I could be doing with my life, in general.
This verse, along with Tim Johnson's favourite parable, gave me just the kick in the arse I needed. I've got a new attitude, and I truly am experiencing great peace, for the first time in a long time.
