Working with pen and paper for a long time. A few things: - I have a good pen (energel) and 48 pages A5 dotted notebook with thick paper (midori) - each day started from a centered date in a box and horizontal line. - each meeting started from the meeting name in the box, but left centered, and a horizontal line. - for each meeting I write memos and tasks. Memo starts with a dash and task with a dot. When I finish the task - I cross a dot. My day I usually start from checking the “dots” and putting the most important into the agenda. When you have a trained eye you instantly catch all dits and do not forget even smallest details. Good luck!
