The trick is to evaluate the future with your current utility, not by the utility of future yous. Similarly, don’t wirehead or commit suicide expecting to live “quantumly.”
EDIT: Actually this might be the wrong trick depending on what you meant. You might have to use the trick of representing multiple instances of a person as frequencies (i.e. not normalized until the end).
