As an in-demand Private Tutor, how do you stay organized?

Interviewers need to hear that you have some method for keeping yourself organized. Be prepared to discuss the tools and approaches you use to stay on track. Maybe you use your Outlook calendar or you keep a detailed to-do list. Perhaps you spend time each morning planning out your day visually and then noting important things to remember. Share the methods you use to keep yourself organized and express how these methods benefit your results as a Private Tutor.
