Often this is done at night looking back over the day, but it can be done anytime looking back over the last 24 hours.
With a slow and curious heart review your day. Look for the stirrings in your heart and the thoughts and actions that have both nourished you and challenged you. How did it nourish you? How did it challenge you? Review your choices in response to both, and throughout the day in general. If you responded well take a moment to appreciate God's grace at work in you, if you feel you could have responded better, that's OK, it's a learning opportunity. Ask for the gift of what you need most to help you. Trust in God and be patient with yourself, God has finished with you yet!
End the time with a thankful heart, and consecrate into God's hands all you future moments.
