Make sure that items are followed up and completed by using tags. You can mark them as Important and add a check box beside your item that can be checked off when the task is complete. Or put a question mark if more information is needed.
In OneNote, click at the beginning of a note that you wish to add a Tag. On the Home tab open the Tag gallery and click on Important and then also click on To Do. OneNote will display a star and a check box to the left of the note. When the task is finished just click on the To Do box and a red check mark will indicate the task is complete.
Or at the end of a note click on the Question Mark tag and type a question beside it. This way you will get your questions answered.
Enjoy OneNote and get results!
