All children need their fathers, but boys especially need fathers to teach them how to be men.
I would have to name two people - my parents. I've seen them come through adversity and work hard to create the best life for me and my siblings. Although I don't remember them together as a couple, I remember the love they had for their children.
Always be involved in your children's lives. Life gets hectic but we have to find a way to always stay connected and let our kids know that they are loved.
Every time I look at my children, they remind me to work harder and become a better man.
