Don't read blogs, or message boards, or Facebook, or Twitter, or anything else today . Ask God to make you aware of how much time you have gained and to show you how He wants you to fill that time.
Prayer reveals to souls the vanity of earthly goods and pleasure. It fills them with light, strength and consolation; and gives them a foretaste of the calm bliss of our heavenly home" (St. Rose of Viterbo).
Ask God to conquer your vanity and inspire you to bring calm bliss to your home on earth so that home becomes a foretaste of heaven for your family.
Go outside and play with your children. Don't just watch them. Engage.
