“Goodness is the only investment that doesn’t fail.”

This quote implies that out of all the things you only are going to keep the things you did well.This may also mean that any bad things you do will just be a waste of your time.They will not help you in the future with anything.Instead in the future it will just hurt your record.It will also affect your reputation if you had one.To add on this quote implies that the things that will only be helpful in your life are anything good you did.For example if you started to sing when you were small that will probably help you.People will get to see that you made a career out of that.Also if you had any good experiences when you are feeling sad or depressed you remember all the good things you did.
