Whatever your hand finds to do, do with all your might… Ecclesiastes 9:10, NIV
This verse goes along with another saying that I know I've heard before, I think from my father: If you're going to do something, do it well. Give it your all! There are a multitude of verses in the bible talking about how we need to work hard, and be diligent. Not only does it provide a good example to others, it can't hurt your reputation. Would you rather be known as the hard worker, or the guy who just sits around and works hard at doing nothing?
