I strongly agree ;).
I definitely think people need to be more thankful for what they have.
I don't have the nicest tack in the world, but then I think, there's a little girl out there that would KILL to have a horse, and that makes me all the more thankful for what I have.
Aaand, no matter how nice of stuff you have, it's always going to seem like there's someone with better stuff, so there's no point in always wanting wanting wanting!!
