I'm not a P (obviously) but the Ps I know -- especially my INTP dad and ENFP friend -- constantly make to-do lists. They probably make them more often than I do, make them more effectively than I do, and stick to them better than I do. I think it's because even though I naturally have a to-do list in my head all the time, they don't, so they've had to train themselves to work that way?
I'm bad at it. I've gotten so bad at it, that I've put important things on my phone's calendar. I only do to-do lists at work, and I can sometimes dismiss it.
I've stopped doing it for anything other work because I will neglect it/forget about it. I sometimes literally need a to-do list to look at my to-do list, and then a to-do list to actually follow through with my to-do list.
I just remembered that I have an overdue library book I meant to return a week ago. It was on my phone's calendar, but after it popped up I became distracted and forgot about it...
I would argue Ps do this more than Js. I think because Js are more systematically minded, they are able to mentally create and order a list, whereas Ps struggle to juggle those things in their head alone. Personally, if I have several things to do, I feel stressed, anxious and out of control because I'm having to force my (naturally non-linear) brain to work methodically. I need to write stuff down to make sense of it.
Also my memory is crap.

I've dreamt in my life dreams that have stayed with me ever after, and changed my ideas;
they've gone through and through me, like wine through water, and altered the colour of my mind.
