I often read Khalil Gibran, and always find his words full of wisdom. "Bread baked without love is a bitter bread that feeds but half a man's hunger"—those who cannot work with their hearts achieve but a hollow, half-hearted success that breeds bitterness all around. If you are a writer who would secretly prefer to be a lawyer or a doctor, your written words will feed but half the hunger of your readers; if you are a teacher who would rather be a businessman, your instructions will meet but half the need for knowledge of your students; if you are a scientist who hates science, your performance will satisfy but half the needs of your mission.
