Be discerning, then be extremely selfish. Learn to hold onto the things that you have invested in and the enemy wants to destroy. Fight to heal a rocky relationship. Fight just as hard in the 7th year of marriage that you did in the 1st, make it to the 7th. Walk through your house, look at your kids, and say "that's mine." Remember the best of your friend when situations become stressful. Discern who is just a relationship and not a friendship.
Be Selfish!!
