I agree. Not only do personal stories give them insight into the working world, they also can serve as a few-minute diversion from lecture. Our classes run for 6 hour each with 75 minutes. That's a lot of listening and they sometimes seem to get bored and/or distracted. Any time that I tell a personal story, they begin to focus again and I regain their attention. It also helps to make you seem like a real person with a personality, which they respect
