When you can't control what's happening, challenge yourself to control the way you respond to what's happening. That's where your power is.
Use your power wisely and control the way you respond. Take a moment to gather your thoughts, say a quick prayer, and by all means make sure you can live "forever" with your response. Use the teachings of Christ as a guide to prepare the best possible response in every situation.
But if any of you lacks wisdom, let him ask of God, who gives to all generously and without reproach, and it will be given to him.
