"Goodness is the only investment 

that never fails."

-David Thoreau 

Some investments may fail and some of them prosper. Goodness is the investment that will never fail. It will always make you rich and feel good.  Goodness by being kind to others and being respectful to others.  Being a good person is the one thing that you should always invest in.  No matter what you do it never fails. For example someone doing good can't be doing bad. Doing good always makes you feel better. Just like you invest in a business and you get money. You invest in goodness and you feel good from it. The difference is if you invest in a business is may not work. Unlike a business  goodness will never fail you. So always make it a point to do good. Also invest in goodness.
