Thankfulness is a state of mind. It should be practiced every day we get to just wake up and take our first breath, because life itself is the most precious gift of all.
I don't think we're bored of our stuff, I think we just don't know what it is we want. Think about it. Always striving, but never arriving. We want more when we could and should desire less. Why can't we recognize we have gone beyond the 'enough' point?
