The Small Catechism teaches us to begin the day with Morning Prayer.

In the morning, when you rise, you shall bless yourself with the Holy Cross and say: In the name of God the Father, Son, and Holy Ghost.  Amen.
Then, kneeling or standing, repeat the Creed and the Lord’s Prayer. If you choose, you may, in addition, say this little prayer:
I thank Thee, my Heavenly Father, through Jesus Christ, Thy dear Son, that Thou hast kept me this night from all harm and danger; and I pray Thee to keep me this day also from sin and all evil, that all my
doings and life may please Thee.  For into Thy hands I commend myself, my body and soul, and all things.  Let Thy holy angel be with me, that the wicked foe may have no power over me.  Amen.

Then go to your work with joy, singing a hymn, as the Ten Commandments, or what your devotion may suggest.
