Anxiety is a pretty chronic thing for me, so when I heard these lines (belonging to Jane Austen's character Mr. Edward Gardiner) while listening to the Pride and Prejudice audiobook, they kinda seemed like a take-away. Granted, in their context, they smack a little of false reassurance . . . but in the context of my everyday life, it's pretty sound advice.
Along the same lines, I ran across this post titled "Brace for Impact" on Seth Godin's blog. It's a good, brief read about, you know, just generally expending too much energy on preparing for the worst thing that could happen (but in all likelihood won't).
I think Seth Godin and Mr. Gardiner would get along like a house on fire. Either that or I've been looking for a chance to use that expression--get along like a house on fire--and I finally just decided to bust it out whether it was a good fit or not.
