Lack of support may hinder your work. Be assertive about your need for study time, and explain to those around you that you have planned for free time that you can share with them. Put your completed schedule in a prominent place so that it will serve as a constant reminder to you and your family of when you have set aside study time. Put it in a place where it will be seen every day and leave it there until studying becomes a habit. As with establishing study time, a good study routine does not just happen.
Much mental preparation goes into developing good study habits.
