Wow. Congratulations. This is officially the dumbest, most convoluted plan to murder a sibling that I have ever seen.

Because that’s what you did. That wasn’t a sad accident. You had a hundred years to think “what can I put in this notebook, what can I say to myself, to make me figure this out on my own?”

Don’t give me any of that bootstrap paradox nonsense, either. You wrote the notes and rules for you. There was absolutely nothing forcing you to make it an exact copy, the timeline would have gotten along just fine.

Frankly, there’s no sensible excuse for you not making it through the years completely unscathed with the benefit of a stable time loop which can preserve knowledge.

I swear, some people. It’s like being chased by a werewolf and refusing to throw a silver fork at it because it would be tacky.
