if you have a roommate that you share rent with, making sure that they will be able to afford your passing (one of the things keeping me here is that my roommate would not be able to afford our apartment rent on her own). if you have pets making sure they have a safe home to go to after you're gone and that they will not be left alone for more than 24 hours after your passing. if you have a job make sure that any outstanding tasks or responsibilities will be covered by someone else, unless you don't care about your employers which would be valid as some employers aren't worth your time. if there is any person whom you are not on good terms with that you don't want to leave on bad terms, you would need to allot enough time to mend those issues. if you have any large or meaningful possessions that you want to go a specific spot at least leave a note with your wishes of where those should go to, if it isn't legally in a will your wishes may not be granted to if there is a way to give them away before ctb without adding suspicion that would be preferable but if not a note is your next best option.
