There's another concept to handling this loss: #FIDO
Should you experience a great loss in your life try this tried and trued philosophy:
Fuck It, Drive On.
This eliminates much stress and prepares you for your next leg of the journey where you realize your mistake and you move on. Or you let go of something that never was a part of you anyway and you rebuild.
Two or three times in my own life I have taken notebooks of writing and I have stacked them up and burned them just so that I could be free of the attachment to those ideas and I could keep writing, start fresh and move on.
Upon your death you only have your actions and the Universe or God keeps a record and eventually that record gets expunged in favor of new energy.
Conversely building a tool that hardens your actions may or may not be valuable too. In this case we must once again be free to go to the market with our actions and reputations to continue doing business.
