One thing that I really found, not only interesting, but really helpful, was the section on sleep. As a college student, that is something that you need. Sleep is important for every aspect of life. It helps you study, it helps your mood, and even helps your attitude. The thing that really stuck with me the most was when it says in the book that you should hide your clock when you sleep so you don't watch the time, sleep in a cold room, avoiding caffeine a little bit before bed, going to sleep and waking up at regular times, avoid naps during the day (the hardest one to adjust to), as well as reading, watching tv, and surfing the web before bed. This is information that I will retain for way more than five years. Sleeping is one third of a persons life, and without it makes your life so much more depressing.
Another thing that I found very interesting is the concept of lucid dreaming, or the fact that you are able to realize you are dreaming in the middle of a dream. I have experienced this before and it is a really weird feeling to have. The concept of dreaming is intriguing in itself, just because it is so mysterious and although there has been a lot of research on it, it is still not very well known. In the end, it sleeping is essential, and still very mysterious, but the parts that are known are going to stick with me forever.
