People take to heart and preserve quotations of things they hear from others which they find of value in some way. It doesn't have to be a quote from someone famous, highly educated, or in any way special, although it often is. Additionally though, some of the most valuable quotes I've found have come from writers via characters in books and movies, and sometimes from some obscure source known only to me and perhaps heard only one time.
Now is a good time to draw on these things we have saved to ourselves and savor whatever value we might see in them. Here is a thread where you can share them with us so we might each find some value in them.
