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.
Oil of Olay has an in-shower body lotion/body conditioner that works better than any regular lotion I have ever used. And I've tried them all. You shower normally, rinse, and what I do is turn off the shower and just use my hands to swipe water off myself so I can get better coverage with the lotion. Then I start from my head and work my way down with the lotion. (Doing it this way saves on product too). When I'm done, turn the water back on and rinse off. The stuff is magical. I have to be careful of things I put on my skin due to some sensitivity issues, and I have zero problems with this. It's stupid expensive and nearly impossible to find in stores anymore so I have to get it online, but it's worth it. After a week of not using it, my skin is a flakey, itchy mess.
They have a version with lavendar and retinol in it now as well, but I haven't tried that one. I just use the regular one.
