When I was younger, I had a steel trap mind. Not anymore. There is a lot going on in my life, primarily with work, and also with medications, and so on. I have tried many things, but the iphone and a couple of apps have been key for me. Plus a 8x7 notebook for spontaneous notes. Evernote is the app I used for notes, drafts, web clips, research on the web for my hobbies. The app Anylist I use for grocery shopping. It can be shared with others, so both my husband and I can update or cross out anything on the list at anytime and whoever gets to the store has a full list. Both apps are free. I do not like technology particularly, but it is required for my work and, once I learn how to use it (long lag phase in learning), it is very useful.
The good thing about the paper notepad is that it fits in my purse and is always with me. I use one per month. All the little notes I take when on the phone, or in a meeting, or talking to someone are in there SOMEWHERE and I can flip through to find them. (ie. I know I jotted down this client's new address, but where did I jot it down???? - now I know.)
My "purse" is now a handwoven backpack from the indigenous Boruca in Costa Rica (they are more famous for their masks.) Having it as a backpack has drastically cut down on the number of times I forget my purse somewhere. I realize there are cities where this might not be safe. I always wear pockets, not matter what and keys go in the pocket. I do not leave the car until I can feel my keys in my pocket. Similar for my cell phone.
