Using this guide is very simple. Just print and read one of the following sections every day. If you see a symbol: then you should read this section in the morning. If you see a symbol: then you should read this section at night, before bedtime. These differences are made because some tasks require you to "notice" events that occur during the day, while other tasks must be performed at night, before bedtime.
It would be nice if you prepared a digital clock with an alarm function, an alarm clock, a notebook and a pen, as well as multivitamins before starting the course.
