This is definitely not ravings of a madman, more like an extremely useful way to think of your self. your self is only this moment, nothing more. Past moments

This is definitely not ravings of a madman, more like an extremely useful way to think of your self. your self is only this moment, nothing more. Past moments are different people who happen to share most of your memory, basically you have one way direct brain-to-brain communication with your past/future self. In this way, doing things that are enjoyable in the moment but have negative consequences in the future, is not much different from doing something enjoyable that has negative consequences to another person in the present. That is to say, both are morally wrong. Ironically, someone with strong moral sense is far more likely to do the first, to hurt the person they can empathize with the most! (because they will literally become that person lol) Maybe some parallel with "hurting the ones you love most", I dunno though I haven't thought that through. Your past self hopefully is like your best possible friend who does favors and generally tries to make your life easier. The future self is a stranger you know you will meet soon, and hopefully you can make a good impression. Present self gets to choose whether to do the right thing or not.
