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

This quote means that if you are good to everyone and everything, then that means that you will get everything right and have everything your way and if you are not good with people, then that would also mean that you might not have everything your way and everything might go out wrong as your solution of answer. For example, if you were going to buy a company and you want the same company to succeed, then that means that you have to try really hard to be nice with people and show to other people that everyone can do the same thing and everyone will do that and the investment that you made to the company will be worth it.
