It's just that... I don't remember feeling like this last year. Lack of motivation, procrastination, apathetic... Thinking to my ultimate goal does give me some motivation for a short amount of time... then it all goes away.
Also, I'm not sure if I'm looking forward to uni or not... I'm sick of all this high school shit.
Hey, don't worry I think everyone's feeling the same at the moment, i know i have - but remember that its only normal. I have come up with a number of solutions to combat this feeling of "burning out" and procrastination.
1. Think back to all the work you've put in this year and ask yourself if its worth dumping it all away
2. Revisit the "why's" - why do you want this? I suggest fantasizing about getting 90 + and imagine the great feeling that will concurr with the sucess
3. Remind yourself that its not about "being the best" but "giving YOUR best"
4. Humans have three basic needs: physical (diet and exercise), psychological (mental well-being) and social (having fun with people). Make sure that all these needs are met because if they're not, then doing well becomes a challenge. Make sure you have a good sleeping time (i sleep from 9:30 till 6:30 during the week and 10-7 during the weekend NO MATTER WHAT), good exercise (i walk to and from school and go gym for an hr every saturday) and a healthy social life. Contrary to popular belief, going out once or twice a month in year twelve is NOT the end of the world. As for psychological needs, try to meditate and think positive.
5. Procrastination is a killer. here's how i combat it:
- i physically write down and answer these three questions: = Where am i and what am i doing? (e.g. i am on my desk watching youtube videos to try to pass time.) What do i "want" to do? = I would love to write up some psych notes. How will I feel after doing it? = I will feel SOO proud of myself. By physically answering these questions, research shows that your procrastination is half way gone.
- Next i write down five things to do: e.g. unpack school books, open up psych book, write heading, highlight key notes, write down key notes. The key to getting ahead is first getting started.
- Finally i ask myself, do i want to watch a silly youtube video OR get a 90 + atar score?
- AlSO always try to reward yourself when you combat procrastination.
Honestly, you seem like a higly motivated individual - relax, chill a bit - do the things you LOVE and you'll be fine

Wish you all the best!
