The devil smiles when we make plans, he laughs when we get too bus, but he trembles when we pray. Don't worry about anything, instead pray about everything, tell God your needs and don't forget to thank him for his answers.
If you do this you will experience God's peace, which is far more wonderful than the human mind can understand. Pray to do the will of God in every situation, nothing else is worth praying for.
Prayer may not change all things for you, but it sure changes you for all things.
