I swear by Blackwing pencils.
Also, the 'two minute rule', which has really improved my life: "if it takes two minutes or less to do, just do it now; if it takes longer, schedule it." I've got untreated attention issues and it's very easy for me to notice something needing done, and overlook or procrastinate it because it seems inconvenient in the moment. Having a totally painless rule that forces me to acknowledge that thing I should pick up, that trash bag I should change, etc, or, to at least put on my calendar anything I mustn't forget in the long run has been great for me.
Zipper cases. These are thin pillowcases that close with a zipper. You then put the normal pillowcase over the zippercase.
Why? Because it extends the life of your pillow. A normal pillowcase can slide while sleeping, etc... which can cause your face, hair, head, body, and all the oil it produces to get on the pillow itself. With the zippercase, you have a second line of defense to keep the pillow fresh.
Sure, you can clean the pillow, or run it through a gentle cycle in the wash, but it is way better to just avoid that. Let the double layer of protection do most of the work and absorb that body oil.
Change case 1 or 2 times weekly, change/wash zippercase weekly. Your pillow will stay fresh and clean and much more pleasant for longer, for a minimal amount of added work of putting that second case on.
And to add on to this - curly-haired people, put a silky case on your pillow. It will not snag your hair nearly as badly as a non-silky one does, which means less frizz when you get up in the morning.
