At the end of each day spend a brief time with the Lord talking through with Him the things that have gone on - asking Him to highlight things for you, particularly reflecting on His involvement in your day, considering where He has been with you and thanking Him. If things come to mind that you are not happy with, ask Him for the willingness and grace to change these, but the end of the day is not the time to dwell on such things, make time for that the next day. This is a long established practice in some sections of the church and is known as Examen.
