buy a pack of chapsticks and put one in the pocket of all of your coats and jackets because you always forget to bring one and chapped lips is sensory hell

leave important things where you can see them. if they go in a box or a drawer you will forget they exist

put any appointments or deadlines in your phone calendar As Soon As you get them. set a reminder for a week before, a day before, an hour before, as many as you need as often as you need them.

when that little voice in your head says "i dont need to write that down, ill remember it" that is the devil talking!!! write it down anyway!!

plan for down time. have a few hours at the end of every day to just do fun stuff like engage in your hyperfixations. even if you didnt get all of your work done that day, have the rest anyway. you probably spent the whole day beating yourself up for not doing what you Should be doing, so you still need the break.

if you never eat vegetables because its too much effort to chop and cook them, get the frozen or canned shit. it doesnt go off for ages and you just have to microwave it. theres no point buying fresh vegetables if they just keep going off and being left to rot in the bottom of your fridge

if you struggle to decide what to have for dinner every day, take the decision out of it. choose a set of meals and eat those on rotation until you get sick of them, then choose some new ones and do it again.
