Whatsoever thy hand findeth to do, do it with thy might.
The Lord doesn’t care for wishy-washiness. He likes dedication. He wants us to give it everything we’ve got. You don’t have to yell and scream, but just see a job through to its conclusion. So whatever it is, whether school work, chores at home, a work for the Lord - do it willingly, cheerfully, and put your heart into it.
