It is all that we want, a feeling of joufullness because someone is appreciating us.
If you actually think carefully, we don't want a lot from life but just a simple thank you!

Like you have said in your post,

embrace the beauty of expressing appreciation

This is exactly what you have done with not only your words but the look and feel of your post.
Well done!

Good luck with the contest, and thank you for the invitation.
