Give, but don't allow yourself to be used. Love, but don't allow your heart to be abused. Trust, but don't be naive. Listen to others, but don't lose your own voice. -Posted for me by my sweet sister-in-law. Love her!
That is an amazing quote. Life is like a piano, the white keys represent happiness and the black keys show sadness. But as you go through life's journey, remember that the black keys also create the music.
