Below is an extract from a senior study guide I have complied that hopefully provides some answers to this problem. The most important thing to remember in terms of avoidance of burn out is to establish intrinsic goals, rather than extrinsic goals such as meeting parent's expectations or beating other people. It is not as simple as giving up, there are a lot of individual circumstances and factors that does need to be taken into account, most of these is a result of neglect to treat these problems over a prolonged period of time that can possibly contribute to individuals truly 'burning out'.
My top tips on how NOT to burn out in Year 11 and Year 12:
1)Establish goal(s) that are either based on individual subjects, week by week, term by term, ATAR, university goals, both short term and long term that you want to achieve during your senior years. Make sure those goals are goals you really want-not those that your parents or friends want you to have-establish personal goals will enable you to have meaningful reasons to keep studying and working hard for the entire year
2)If following a study timetable is not working for you, then try a to do list day by day listing all the things you must do and other optional things you need to get done-school work and other commitments-avoid procrastination, for example,by using surfing the internet as a reward another a successful study session, keep the reward to 5-10 minutes for every 45-60 minutes of high concentration study.
3)Enforce some self-discipline, perhaps group study might work for you-perhaps you need the occasional encouragement from your friends-but don't get distracted, whenever you want to give up, rehydrate your brain with some stretching and cold water, and visualise yourself at the end of the HSC year, achieving all the goals you want, and having no regrets. Smack your desired ATAR on the wall-and whenever you feel quickly tired, have a 5 minute break and look at that number-and think to yourself-if you want that ATAR, you will just have to keep working hard and keep studying
When people burn out-it is usually because either they have irregular sleeping routines or they lack self-discipline that comes from lack of real motivations. Make sure you sleep and rest well so you are alert in your study, eat healthy food, exercise and find some genuine, intrinsic source of motivation and that way, with persistence, consistent optimistic attitude and determination, you will maximise your potential and improve your academic results in the senior years.
