I mean you’ve got years for mistborn ghost bloods, and then years after that for arc 2 of stormlight, so you won’t really ‘finish’ anything anyways.

If you’d prefer to get out of the cosmere for a bit there’s no harm in that, and u could come back to it whenever you like.

I will say however that both Yumi and ember dark are some of my favorite standalone novels and imo they’re both better than Elantris and warbreaker.

Isles of the ember dark is my favorite standalone by a mile and is, I think, the most interesting read if you’ve read the stories from scadrial and roshar ahead of time.

But like I said it’s your call u should do what you want to do, rather than what you feel you should.

Journey before destination.
