Bill Hybels, Senior Pastor at Willow Creek in Illinois helps define the 'diligent worker' in the book of Proverbs in the Bible:
"A Diligent worker...
Shows up on time
Determine what's expected
Takes responsibility to get better
Honest with time"
So make sure you are a diligent worker and not a sluggard. After all it's the right thing to and it models the way for others.
