Contentment is not the fulfillment of what you want, but the
realization of what you already have.
I bought a card for my husband about 24 years ago that had this verse in it. He never really did "get it" and sadly has spent a very large portion of his life searching for the material things he thinks he needs, never realizing what he already had. So sad.
I have so much to be grateful for; we all do. We just need to realize it.
