Oooh I love the idea of talking through tasks as you complete them to remember!!
Also I agree about spending on a coffee maker with auto shutoff. To me it is *always* worth saving up for the item that makes my life easier. I have timers on several lights in the house that I used to forget to turn off all the time.
And for keys and wallet a command hook by any main entrance doors or a basket as soon as you walk in is a great location to make a habit of putting those things in one spot.
