If you haven't applied for scholarships there's still time. Apart from that just study for the HSC and enjoy being a senior in your school.
I was pretty sentimental when graduating but I very rarely think back on highschool now.
General life tips for someone about to graduate:
- You will probably stop hanging out with most of your highschool friends in 6 months. That's completely normal.
- Having a daily routine of keeping your environment clean as an adult is extremely important to your future academic and career success.
- You should try to enjoy 18-21 while still being moderately responsible. You can get away with significantly more at that time. I don't recommend becoming overcommitted to the grind because burn out in your mid 20s is a real thing.
- There may be better barbers than the one you currently use.
- Dont catch nightrider busses.
