glad i'm not the only one suffering

Could shard of my soul be a reference to something similar to how there are bits of Preservation in people on Scadrial or how there are bits of Endowment in the people on Nalthis?

if i remember correctly when you store memories in copper you forget what you stored so maybe when you compound you create copies of the memory this allows you to remember the memory and instantly store the memory so it doesn't degrade. And if you keep compounding you are always taking memories out and putting them back so they are always fresh in your mind and the copy in the metal mind never goes bad from being in you mind to long. This could be how the lord ruler had perfect memory. It is possible to vary somewhat how quickly you burn your metal allomanticly. So maybe you don't have to compound copper enough to give you 10 times. You only need 2 times the memories for what I explained and then maybe the copper wouldn't burn as fast.

what if when you soulcast it basically replaces each "stone" atom with a "smoke" atom. When I say atom i just mean the basic building block that makes up smoke. That could be a molecule, a set of molecules or maybe the cosmere doesn't even have the same subatomic structure as our universe . So in the instant of soulcasting the block of smoke has the same volume and the same density of particles(but not the same mass because a smoke atom has less mass), but the smoke is a gas so it will try to spread out evenly in the surrounding air.
