Chapter six was about how life can be viewed as a temporary assignment. We must remember that the length of life on Earth doesn't compare to the eternity we can spend in Heaven, so don't get too attached to worldly desires. I like how Warren compares our life on Earth as simply a visit or travel, and that we as Christians should keep our "spiritual green card", meaning our actual citizenship is in Heaven. We should not live for the here and now. We should not "flirt" with the world, or we can get caught up, and our God is a jealous God. "Don't indulge your ego at the expense of your soul". Consider life as just waiting to go home, but don't get distracted and miss the ship when it sails.
