If you currently make notes to yourself on paper (post-it notes, notebooks, etc) you can use Microsoft OneNote to make electronic versions of your notes, which you can then access from all of your devices and share with others. Notes can be typed or handwritten if your device supports it. Apps are available for Windows, Apple, and Android devices. OneNote is part of the office suite if you have it installed or you can access it via OWA.
