A sluggard's appetite is never filled, but the desires of the diligent are fully satisfied. (NIV)
The appetite of the sluggard craves and gets nothing, but the appetite of the diligent is abundantly supplied. [Prov. 10:4.] (AMP)
The soul of the sluggard desireth, and hath nothing: but the soul of the diligent shall be made fat. (KJV)
