I am not suggesting any particular belief system here, but I really like the ideas in this prayer. This prayer was given to me by my friend at work, Krystyna.

PRAYER BEFORE STARTING WORK

My Heavenly Father, as I enter this work place, I bring Your presence with
me. I speak Your peace, Your grace, Your mercy, and Your perfect order
into this office. I acknowledge Your power over all that will be spoken,
thought, decided, and done within these walls. Lord, I thank You for the
gifts You have blessed me with. I commit to using them responsibly in Your
honor. Give me a fresh supply of strength to do my job. Anoint my
projects, ideas, and energy, so that even my smallest accomplishment may
bring You glory. Lord, when I am confused, guide me. When I am weary,
energize me. When I am burned out, infuse me with the light of the Holy
Spirit. May the work that I do and the way I do it bring faith, joy, and a
smile to all that I come in contact with today. And oh Lord, when I leave
this place, give me traveling mercy. Bless my family and home to be in
order as I left it. Lord, I thank you for everything You've done,
everything You're doing, and everything You're going to do. I pray, with much love and Thanksgiving..... Amen.
