" Goodness is the only investment that never fails." by Henry David Thoreau

What this quote means is that doing good brings you happiness and joy.You might invest in something, a school, store, or maybe in house , they might fail but goodness wont.You will be well known and will gain the trust of many as long as you do the right thing to do.An example might be you trying to invest in feeding the homeless or donating. They might not go as planned but what matters is the action that was trying to be made.
