I personally don't believe you need to MM everything, especially if it's already in outline form or in graphical form.
I went to school where the majority of the lessons were taught on MM's and I hated it. I could not wrap my mind around it. I always ended up making my own linear notes from their MM's.
Recently I revisited the MM book and downloaded some software and realized that they weren't so bad afterall. It doesn't work for everything though (to me) and it can be time-consuming. It's worth it if it's a lot of concepts.
For me, learning bones & muscles was best done with 3x5 cards.
