Has someone gone out of their way to help you or someone else? Has someone just said something that made you feel better? Are you simply thankful because someone or something made your day a little brighter.
Well how about showing your gratitude with a little thank you note or writing in a gratitude journal.
"Gratitude is a quality similar to electricity: it must be produced and discharged and used up in order to exist at all" ~William Faulkner
