Add projects you're currently working on; note down open questions, tasks, links and files. You can also create a new map for each big project and place a link to it in your main map.
Note down everything you need to do TODAY. This list should be updated on a daily basis or whenever you've finished a task from the list. You can either check it off or delete it right away.
Note down everything you can't do right away but need to remember for a later point in time. You can also add dates and link them to your calendar.
