Ungrateful people forget what they are not grateful for.

Making the ungrateful grateful will bring tears to your eyes, tears of blood bleeding from the heart.

Making the ungrateful grateful is a tedious endeavor.

I see the glass half full and thank God for what I have.

Good for you and be proud of yourself because you have your priorities in order. Be proud of yourself if you are responsible, reliable, persistent, and take your job and education seriously.

I'd rather hear an ugly truth, rather than an obscure lie.
