What's the line between diligence and sloth? Balance.
This Labor day weekend, don't forget to celebrate the joy that can be work, given the proper perspective. The Lord gave Adam the gift of working in the garden - a good occupation that provided structure and meaning to his waking hours. Yet a planned day of rest was also a gift.
Don't forget - be thankful for your work, whatever it is, and be thankful for rest. And don't forget to get some play time in too!
