Whether your glass is half full or half empty, hope can fill it up.

The optimist sees the glass as half full, the pessimist as half empty. What I see is water that can save someone's life.

A negative outlook is dangerous. When you say, “It can’t get any worse!” You're essentially challenging the universe to do exactly that.

Whether your cup is half-full or half-empty, remind yourself there are others without one.

I think I sense a tone of honesty, if honesty exists in this world.

Don’t settle for a half empty glass, always go for a full one!
