I very much like the prayer-
"O Lord, grant me to greet the coming day in peace, help me in all things to rely upon Your holy will. In every hour of the day reveal Your will to me.Bless my dealings with all who surround me. Teach me to treat all that comes to me throughout the day with peace of soul and with firm conviction that Your will governs all. In all my words and deeds, guide my thoughts and feelings. In unforeseen events, let me not forget that all are sent by You. Teach me to act firmly and wisely, without embittering and embarrasssing others. Give me strength to bear the fatigue of the coming day with all that it shall bring. Direct my will, teach me to pray. And, Yourself, pray in me. Amen."
Which I think is by Metropolitan Philaret. Is this widely used today by Orthodox believers?
