If you could go back and tell your teenage self one piece of advice...

[Moagim]

Engineering is hard as hell and you are not going to get past second year if you don't start studying 4 hours a day.

 

[Last Hugh Alive]

I'd say: It doesn't fucking matter if you never find the dream job you're supposed to be totally passionate about. Just get off your ass and do something and find your thrills in your personal life. Don't fret over not being good at shit, just take a step forward in any direction and opportunities will open up. Keep on being yourself and don't be afraid of screwing up.

 

[Finbark]

She doesn't actually like you bro. Just leave her now, and don't be such a massive pussy about it. You'll save about 4 months of your life that could be spent enjoying things rather than moping around like a depressed idiot.
Oh, and lay the fuck off the soda and salty-ass food. Seriously, just because you're not getting fat doesn't mean it's not hurting you.
Stop being such a lazy piece of shit, and start putting in work at school. Honestly your life will go so much more smoothly.
And start working out, good God you scrawny, non-athletic fuck.

 

[JoesshittyOs]

Uh... Fuck em. Pretty much. Fuck em and do it with a smile. Oh, and work on that "being nice" to people you've never talked too.

Don't do something that you think will cause drama during a break up. Yes, your anger is completely justified. Yes, she's the textbook example of a backstabbing *****. But it works out much better if you do everything in your power to stay the reasonable and understanding guy, for the love of all that is holy.

Edit: Ehh... as cautious as I am about saying this, avoid Facebook. Seriously, it's like internet crack and it is never entertaining. You'll end up hating the people you already hated even more. And it gets you in trouble.

 

[Right Hook]

Past Me: Who the fuck are you?

Future Me: It's late 2008, right?

Past Me:...yeah? Dude, are you me...from the future?

Future Me: Good, so I wasn't a total moron. Anyway, you are about to go through a lot of shit that will seem important now but trust me it isn't...like at all. Back your true friends even though they are total morons right now, just like you. None of it for like the next 3 years will matter that much, it's even fairly dull now but I've been changing things. Unfortunately that's about all the OP will let me say...

*starts to walk out*

Past Me: Oh! You've gone back and told Abe Lincoln to enjoy that play, right?

Future Me: *****, I got a time machine! You know I did that! Oh, and don't be so modest, you are fucking cool as hell, prick.

* Disappears in huge cloud of time travel smoke*

 

[BiggyShackleton]

If I could go back to about 13 I'd say, learn to play the guitar. By the time you hit uni the bitches will be powerless to resist.

And pay more attention in French lessons.

 

[Sonicron]

*Ahem...*
Dude, lay off the fatty foods. Seriously. The diet you'll be doing at 25 is a pain in the neck.

 

[Smithburg]

Study, work hard, don't be lazy and stop thinking you're worthless. (Granted, I'm still this way, but maybe me telling myself from the future that would knock me out of it)

 

[lionsprey]

put down those chips also you have ADD.

 

[The Pinray]

Do your homework! And shave god dammit!

 

[Kae]

Uh, I don't know the things I would have liked myself to not do are the things that made me become the person I am today, doesn't really matter how wrong they were and how much grief they caused me, or what an awful person they made me back then, but in the long run they kinda made me the person I am today, I wouldn't have such strong moral standards or be this nice to other people if I hadn't become afraid that I was turning into a monster, I mean as many nightmares that time that I almost killed someone brought me, I think I could be an awful person without that life experience, I don't know I quite like who I've become and I wouldn't want to risk not being me, even telling myself to stay in school would change too much...

 

[game-lover]

Get a job. Get a job. Get a job. Get a job. No one expects experience when you're that age so they won't ask for it when you apply. It's perfect. So get one. Yesterday.

Also, apply for scholarships. They're better than loans and there's a lot more for high school students than undergraduates. Pretty sure they're easier too.

 

[Shuguard]

Dear self, practice 20x harder at rifle spinning until you are good enough to win County, State, and Nationals (JROTC).

and DO NOT loan The Elder Scrolls: Oblivion to your friend.

 

[phantasmalWordsmith]

Its no use thinking that you're wrong. The past is dead and gone, its best to move along and find your avalon

 

[Snowbell]

There's much better guys in university; wait until then to go out with one.

 

[iseko]

A) DONT start smoking
B) Fuck her then dump her. Trust me on this one. Seriously.
C) Get a haircut

 

[The Last Nomad]

Smoke more weed. It won't hold you back.

And Cheer the fuck up. You won't need to be depressed til much later in life.

EDIT: although the first would cancel out the second. As it already did, but not early enough.

 

[Mariena]

"Hey, it's me, from the future. Just wanted to say, keep up the good work. Bye now!"

*poof*

 

[albear]

Kill them all, it doesnt get better, it gets worse, alot worse, kill them all

 

[Rastien]

Dude that pain in your guts which is going to happen around 17, DON'T IGNORE IT!. Its a really serious disiese and you don't want to end up in intensive care for 2 weeks and shitting out a hole in your side into a bag for a year till they fix you back up.

Hm... oh and yeah don't burn your bros girlfriends ear with a cigerete when drunk she wont forgive you for it and will break up with your bro.
