The best leadership is by example. Make sure you're staying productive, industrious, responsible, and considerate. Set reasonable standards for your child and hold him/her accountable. My grandfather probably influenced me the most in that area. Whether I was doing homework or chores, he'd only tolerate my best effort. He used to tell me "do every task like you're doing it for God." and "if it's worth doing, it's worth giving it your best." One of his favorite sayings was "we're all in this together", meaning we're a family and we're all responsible to each other. Nobody sits around while others are working.
