Stipulations:
- You cannot die and are immune to disease
- You cannot alter the future such that you change the world from your point of origin. i.e. You cannot become so famous that future people recognize you as immortal.
- If you vary the timeline too much you will cease to exist.


You cannot change it so much that you alter the future. Doesn’t mean that you can’t live a fulfilling life or run things from the shadows.
But the catch is I dont know what will change time a lot or a little. If I get in an elevator and shit my pants in front of Utada Hikaru does she never write Simple & Clean? I simply cannot know, so with those rules I have to isolate.
Why not operate under the assumption that your future self has already gotten away with everything? Taking advantage of the bootstrap paradox. Like Bill & Ted, everything around the dad’s keys. Might at least be fun, that way.
She would certainty nor say that simple and clean is the way you are making her feel.
