Your description of the struggle to find a method to organize fits me to a tee! I’ve tried a few different apps on my phone because I almost always have it on me (except recently I’ve been misplacing it more – God help me!!!). I’m currently using Google Keep. I like it because once you start a note you can click on the microphone and create/add to your list. I remember things while in my car and add it before I forget it. You can set a reminder on the phone to look at it to review (to keep me from “losing” the note). I sync it with Google Drive so I can access from anywhere. It’s not perfect, but what is? It took a little while to get used to it. When I had a little free time I played with it to see how it worked. Hope this helps!
