"Goodness is the only investment that never fails." 

Henry David Thoreau 

       This quote means that the amount of goodness you do and invest in will never fail. It will succeed and flourish into something even better. It doesn't matter how much goodness you do, as long as you never choose that wrong. This is really important because it shows that if you want to become greater than all you have to do id good and you will never fail. If you see that you are going downwards and not succeeding that there is something your doing wrong, that's choosing the wrong. You need to fix that and do good to never fail. I agree with Henry David Thoreau because he is telling the truth, if you invest in doing good then you will never fail you will only grow and stay positive. For example you see your sister or brother having trouble studying. You either ignore them and let them struggle or help them out to learn and get a good grade. In order to not fail you choose the right and do good, which is to help your sibling out to study. If you every try doing good it doesn't matter how much you do, it matters if you chose to do it or not. And if you do you will never fail.
