I hope, Sam, and I suggest, that in addition to reviewing where and how you "failed miserably" during the course of a given day, that you also pay attention to the successes, large and small, of each day: the times God spoke and you listened; the times you saw Christ in a neighbor, co-worker, friend or family member; the times you were Christ for someone else.  I think this is a critical -- and for many of us a difficult -- part of the examination of conscience, because if you examine only where you failed, you are not fully appreciating what God is doing in you and through you.
