"I am grateful for my memory." How often do you hear people saying this? Do you hear this more frequently or do you hear something like this, "I can't remember. I'm always forgetting things. My memory isn't what I would like it to be."
Hopefully after people read this section, they will develop the habit of consistently being grateful for what they do remember. And they will express this gratitude so frequently, that others will also develop the habit of expressing gratitude for their memory. And many more people will hear those people expressing this gratitude, and they too will express their gratitude.
(From Rabbi Zelig Pliskin's book: THANK YOU! Gratitude: Formulas, Stories, and Insights: Artscroll Publishers)
