Appreciate

Saw this today and it made me stop. That damn cup and being half full or half empty, sometimes it taps me on the shoulder and sometimes it smacks me in the head. I ask myself, why is gratitude so hard? Why is seeing what isn't, easier than seeing what is? Why do the negative tapes play louder and longer in your head than the positive ones? Am I the only one who suffers from this affliction? Is there a cure?
Right here...right now...in this moment I appreciate all that I have...and I say Thank You!
