Statements like "How did that become important to you?" or "Tell me more" can elicit a story from someone and show that you're listening and curious, writes Dan Rockwell. Keep questions short, and avoid making assumptions or casting doubt.

Self-control seems like an admirable trait, but it can often lead us to feel overwhelmed, alienated and biased against others, write professors Michail Kokkoris and Olga Stavrova.
