Marie Forleo, a mentor and founder of the popular online Business School says to schedule everything on your calendar. If it is not written down and scheduled, it is not real. I have found it very helpful to use both my iPhone calendar and a paper calendar to keep my schedule. I like my iPhone because it will send me reminder notices on my phone before a scheduled event. Since I am very visual, I also like to be able to see a paper calendar with everything scheduled to help me see the bigger picture.
