advice for my younger self

I looked at the calendar today, and realised: my last class of highschool is next week.

MIND. BLOWN.

Not to be cliché, but... time really did pass quickly. (Except for during many of my classes. I'm pretty sure I could have skipped them without too many regrets... If only I went to a school with more students, wherein my absence would not be noticed. Or at least one at which my mother didn't teach.)

However, looking back, I noticed quite a few things I'd change. Unfortunately, as I do not have a Tardis, they'll remain regrets... but I thought I'd compile a list of advice I'd give my eighth-grade self, before coming to high school. Just in case.

1. Breathe. Ask yourself, "Is this really such a big deal? Will I remember this in a couple of years?" The answer is usually Yes... Yes, you'll remember it because you stressed way too much about it. Just chill out. (Picture your older self wearing hippie glasses and waving a palm leaf... for some reason that's the image that comes to mind when I say chill out. Who knows why.)

2. You don't have to get along with everyone. You know those people you think are mildly annoying but you think you should talk to because they're in your class? Don't bother. You can make better friends elsewhere.

3. But on that note, do actually try to make friends. Books are lovely, but socialising is important too! Just pick people you actually have interests in common with.

4. You have the power to change things. Mostly, this means: pluck your eyebrows. It is a Big Issue in your life, and it's not a big deal to change them, so DO IT.

Or in a more deep way: the world is yours, so go get it.

5. ...but if you can't change it, walk away. You know all those situations you felt really uncomfortable in? You're allowed to leave. Don't think you have to stay somewhere just because everyone else is.

6. Trust yourself. If you think you're going to hate something, assume that you're right and don't do it. (I'm thinking of all the 'school-bonding' activities that I attended. I can't think of one I enjoyed, and yet I went to quite a few... seriously, just don't do it.)

7. You are likeable. Don't assume that you're entirely forgettable. You're worth more than that. (You probably don't believe me, and I don't really believe myself in typing it, but I'm hoping that it'll come true by repetition.)

8. Don't allow your mother to buy you uniform shirts. She will buy you the wrong size, and the result will be that you're miserable for over a year. (They don't shrink that much, and I didn't grow that much. I am not an elephant.)

9. Keep in contact. You know those people you met, and liked, and... never talked to again? Yeah. Send them a message! A letter! A text! It's not that hard, and it might be awkward at first, but really, what do you have to lose? (Confession: I am so bad at this. Still. Which is why I'm putting it down in writing.)

10. Exercise is your friend. You know how you always think you're too klutzy to go running/dancing/move in general? Well, the more you work on it, the better you'll get. (You'll probably still fall down quite a lot, but you'll do it gracefully.)

11. Don't study so much. My studying schedule went like this.
Grade 9: "OMG if I don't study this for hours I will fail and my life will be forever ruined omg must spend hours doing this"
Grade 10: "Hmm I should probably write an intense study guide. I can use it to review next year!"
Grade 11: "Okay, I'll review and rewrite some notes..."
Grade 12: "I don't understand this and I really don't care. I'll still pass and get good grades."

...and every year I did almost equally well. (This goes well with no. 1- just chill out. The only important grades are some grade 11 ones and some grade 12 ones anyway... so really my schedule should have been reversed. Whoops.)

12. Do your own thing. So what if other people think it's lame? You'll have way more fun.

I wish I really did have a time machine so I could send this back to who I used to be- I think it would come in handy. Plus, some of these (especially nos. 1 and 9) are still things I need to remember. What's some advice you'd give your younger self? Do you have any university advice for me?
