The D-I-Y templates, in my opinion, are a complete waste of time. It takes 10 seconds, for instance, to create your own handmade weekly calendar card. (Draw 6 quick lines across the card to create 7 spaces.)
The hipster PDA is great if you have a lot of thoughts you want to capture. If you have a stack of index cards, you can afford to jot down one thought per card. Then type your notes into a text file; or organize your notes into categories, subcategories…
Use a notebook if you don’t want to have any extra organizing and/or processing work. But use index cards for maximum flexibility. Pretty soon, you’ll have a big file of cards (organized by subject) that you can browse, use for papers, etc. Going through the cards again helps you remember what you wrote down.
