, write down everything about your current activities for a balance between your studies, social life and sleep. For example, I write down the important dates or event that I cannot change with red pen such as small quizzes in the class, homework due dates, mid-term exam, and final exam and so on. After write the importance things I also note down my daily activities that can be flexible with blue pen for example, when I have lecture or go for dinner with my family or even when I eat and go to sleep. Therefore now I can easily see if there are any times or days that I can study or when I can slip an hour of devoted studying.
