Best investment you ever made. When I was a boy my dad had a delivery route. He used to let me work for him to earn extra money to buy a bike or whatever. Anyway, one stop was an old folks home. I used to look at those folks and wonder why they were so lonely. Where were their families? I had great parents, and they will never be alone at the end of their lives. They will live with me and their grandkids as soon as they need physical help. My point is, the sacrifices you have made financially will pay off more than any 401k ever could. Most of the problems we face today can be solved by father's. Congrats my brother, enjoy watching your kids flourish.
