From YOUCAT, fact 499:
499: When should a person pray?
From the earliest times Christians have prayed at least in the morning, at meals, and in the evening. Someone who does not pray regularly will soon not pray at all. [2697-2698, 2720]
Anyone who loves another person and all day long never gives that person a sign of his love does not really love him. So it is with God, too. Anyone who truly seeks him will keep sending him signals of his longing for his company and friendship. Get up in the morning and give the day to God, asking for his BLESSING and to “be there” in all your meetings and needs. Thank him, especially at mealtimes. At the end of the day, place everything into his hands, ask him for forgiveness, and pray for peace for yourself and others. A great day – full of signs of live that reach God.
