OK, not sure about that "time of your life" stuff, but the rest is pretty accurate.
You Are High School You are very busy these days, and generally you are happily engaged with the world around you.
However, you still have a rebellious streak, and you get annoyed by authority. You would prefer to make your own rules.
You live for today, but the future is looming more and more. You are a little bit [lot] scared of uncertainty.
You are having the best times of your life right now - times you will remember forever. Every moment seems extra poignant.
