It's not something you're likely to do any time in the near future, is it? Who wants to invest in cemeteries? Sure, we use them a lot, but invest in them?
So here's what you do in fact do: you spend a lot of time in your dead history. That's like investing in cemeteries. You live in those moments of your past that caused you pain of some kind, because you are still invested in them. For some reason you still feel you get a payback by going to those past events, and particularly by going to those past painful emotions. In some sense, you have fashioned your identity by building on the pain that was created in you during those past events. You are still invested in them.
Would you not prefer to invest in the present, in order to create a better future? You can do so by deliberately choosing to leave the past behind. What makes it so difficult for so many people is not leaving the past behind, but choosing to do so .
Make that choice today. For yourself, for your family, and above all, for the future that will arise from this choice as opposed to the future that would have arisen if you did not make that choice.
Tomorrow is built on today and if your present moments are filled with investments whose dividends arise from painful memories, that cause pain right into the present, then your future will be painted in those colors.
