Do you have a good memory? I don't... But I use about 4 different notebooks and that helps! ...(some made more for sketches, some for texts), they only have to be small enough so that I can carry them with me everywhere! I need paper & pen for that. A keyboard to take notes? no way.
(do you realise I show you part of myself here? It's very intimate, almost pornographic! :P)
PS: I only realise now I almost never take notes in French! How weird is that!?!
