I think the most important thing that we can put on while we are getting ready for work, school, or wherever, is to put on the full armor of God. 

"Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, and with your feet fitted with the readiness that comes from the gospel of peace. In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. Take the helmet of salvation and the sword of the Spirit, which is the word of God." (Ephesians 6:13-17 NIV)

Just as we go about our daily routine I believe The Lord wants us to put on our armor daily as well. 

This chapter in Ephesians also goes on to say, "And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the Lord’s people." (Ephesians 6:18 NIV)

Right after the armor of God is listed, verse 18 tells us to pray. Although it's not specifically listed as part of the armor I think it's important that we cover ourselves in prayer too. I love how this scripture encourages us to pray "in the Spirit on all occasions with all kinds of prayers and requests". That is so encouraging. We can come to God just as we are and there's nothing we can't talk to Him about.
