I don't understand this at all. Do you also think like this about the "future you" that might have to shit themself on the bus ride if you don't go to the bathroom before you leave?
I don’t think you understood what the GP said, but then you claimed as much…
That said, even with your interpretation, imagine that if you didn’t do something, somebody else would have to shit on the bus —- you’d have to be pretty selfish not to spend a bit of time to spare the other person of the embarrassment.
There are myriad other examples where you can take action now to avail yourself of a future mild inconvenience that you might not take if the inconvenience were experienced by someone else instead. And I can't imagine that you think telling me I don't understand what GP said, without offering clarification of your own, is a useful comment.
Why set your future self up for success if your only connection to that person is a story in your head? What is supposed to change when you take this view of being disconnected with your future self?
