That relies on you being able to acquire this C4 without the authorities noticing and putting a stop to it.
C4 is the easiest for this example. I can definitely manage explosives. You can rather easily make things which blow up.
Let’s make this easier then, I go to the woods and set up a huge fucking boulder on an elaborate pulley system (don’t worry about me finding them, I live in Finland were boulders and rocky surfaces are a plenty. My cousins actually operate a gravel business, so they have lots of proper gear for breaking rocks into smaller rocks, and vehicles to do those things with. So let’s say there’s a pit. I lay a ton of harsh gravel on the bottom of it, a proper few meter layer. Then I take a loader full of massive boulders. And another. And a third one. Place them around the pit. Place myself in the pit, and remotely activate the loaders to drop all those boulders on me. Oh and I didn’t mention, but I put a bed in the pit with me. It’s a bed of extremely sharp knives, covered by a thin cardboard so I don’t get stabbed if I easy myself onto it. On top of that, there’ another bed, upside down, also loaded with insanely sharp swords. All of the boulders will fall into the pit, crushing the bed system, which stabs and slices me into pieces while the boulders to the rest of the work. (The bed frames are soft enough so that they can hold knives, but will be utterly deformed by the boulders so they won’t stay in the way.
Then I’ve also paid for a crazy cousin to empty both barrels of a shotgun to my face with a full metal slug right as the stones start dropping.
But… I’ll survive?
This again assumes you can successfully pull this off. Get into an accident on your way to the woods and get paralyzed from the neck down? Too bad, you live now. Crazy cousin has a sudden moment of clarity, recognizes the insanity of what you’re doing, then has you committed to an asylum? Too bad, you live. Spend a few hours toiling to set up your contraption, collapse in a puddle of exhaustion, then have a change of heart because why the duck are you putting so much work into trying to off yourself? Well, then you live.
Paralysed from the neck down.
Then how am I gonna run the marathon?
So you’re saying you have no free will whatsoever, but despite whatever happens, the prophecy will be true?
That I could never drive an older car pretty much, because it’s easy to kill yourself with one. Much less a motorbike without a helmet.
I can never hold anything sharp which could cut the jugular. Couldn’t manage to go swimming, because diving deep and inhaling would somehow have to fail?
Either the prediction is bullshit, oooor it gives you magical plot armor (unless it’s extremely vague, but that goes against OP’s description),
