Build yourself, on either a virtual or a paper tablet, what’s known as a commonplace book—someplace you can copy down bits of writing you encounter and find clever and/or meaningful—and keep it handy for future use, even if that future use is simply your own edification. (Don’t forget to make note of where you found the stuff.) Then at least, should you find yourself in a position to share with the world your own wisdom and want to periodically sprinkle it with others’ smarts, you’ll at least have something fresh and heartfelt to offer.
