He might not say it very often (if at all), but your son looks up to you. You're the primary male influence in his life, so virtually everything he's going to learn about being a man is going to come from you. Keep this fact in mind when the two of you spend time together. Lead by example. Show him how to be a humble winner and a gracious loser. Teach him the value of hard work and the importance of seeing projects through to the end. This may all sound a bit cliché, and you can be a spoilsport and a sore loser and still bond with your boy, but you'll teach him so much more by showing him how to act like the man you want him to be. Remember that you're more than your son's dad -- you're his role model.
