The future is known only to God, and therefore it is impossible to say with certainty how circumstances will turn out. People make plans, but it is God alone who disposes fate.
Ambrose of OptinaMore Ambrose of Optina quotes
Throughout the day, try to remember God more often. If you feel bad, turn to Him: "Lord, I feel bad, help me." If you feel good: "Lord, glory to You, thank You for this joy." If you are worried about someone: "Lord, I am worried about him, help him." Whatever happens, turn it into prayer.
