“...if you live feeling likeYour glass is half empty, well,It may as well be empty all the way.”
“Glass half empty, glass half full. Well, either way you won't be going thirsty, count your blessings not your flaws...”
“The glass is not half empty; it is half full.”
“You should never look at the cup or glass as being half empty; see it as being half empty, then you will have mastered the test of greatness.”
“Half full or half empty, just be thankful if your glass has anything in it at all.”
“Don't bother. The glass is half-empty.”
