The secret of going on

Why get excited over these small things? or let them disturb you? If you remain quiet, things will go much better and, if there is any difficulty, you are more likely to find out a way in a quiet mind open to the Peace and Power. That is the secret of going on, not to allow things and happenings, not even real mistakes, to upset you, but to remain very quiet, confiding in the Power to lead you and set things more and more right. If one does that, then things do get actually more and more right and even the difficulties and mistakes become means for learning and steps towards progress.
