“Goodness is the only investment
that never fails.”
-Henry David Thoreau
I think this quote is trying to say that acts of kindness is the only action that will always lead you to success every single time. Cheating and lying may lead to success at times but once you are caught, you will fail from that point on. Goodness must be one of your building blocks in order for you to succeed. If you do use it as a building block, you will be able to accomplish anything you set your mind too.
