A major difference between learning Modern Greek vs Ancient Greek is that with the former you can find someone to speak Greek with.
Learning Greek from a text book can be a little discouraging but you have a huge advantage in being a Textkit member. Being able to ask questions etc maybe all that is necessary to stay motivated.
If your textbook does not explain English grammar at all, you may have to brush up on it in order to understand the Latin (or Greek) grammar.
I wish you success.
There is absolutely, positively, unquestionably, etc., no reason to learn Latin, unless, of course, you’re scheduled for an upcoming lobotomy or forever foaming at the mouth! Shame on you for even considering Latin over Greek.
Alas, you are young, so you are forgiven.
Now go and learn Greek before I tell your parents. 
~Peter
p.s. As you can obviously tell, I am still pissed off with the crusades, particularly the fourth one.
Which is easier?!?! Thats all I’m going by!
I always maintained and will continue to that Latin is somewhat (at least) easier than Greek.
This sort of reaction from the good bishop has become commonplace. Unfortunately, our young visitor still has no idea this is how you speak, Episcope. I shall translate, for this is E’s way of saying keep at it:
There is no comparison with learning when you’re young. My advice, don’t let anyone spoil that for you. At the risk of sounding obvious, you only get your youth once. Take full advantage of it in every sense. Can’t spend all your time in books, but books shouldn’t be discarded either. At least I wish it were so for me when I was your age. Your desire to learn is amazing.
Come to these boards (and ignore E. when he’s feeling cranky) with even the silliest questions. There’s no end to how ridiculous my own questions are. If you like, private message some of the members who are more than happy to help - you should get an idea of who they are rather quickly. I can’t help till the 30th of this month; even now I feel guilty for focussing on this instead of school.
(He got about half of them flaming people and making outrageous claims like ‘I am better than Cicero!’; every two or three hundred posts he gives, he allows his human side, vulnerable like the rest of us, to shine through. Don’t let him discourage you, pjj.)
I suppose this is really the Cavalier’s labour of love, but since he hasn’t said it yet, I’ll mention you should consider Lingua Latina (and Latine Disco too for explanations in English, though I myself haven’t read it either). LL is brilliant.
Somewhat? That would be a leviathan somewhat. Einstein was able to rock the scientific world off its feet, yet he couldn’t handle the Greek verb system.
Ah, my dear young man of 13, if it’s easy you want, then go with Latin.
You’re not planning to be a doctor, are you?
I wish I had started learning latin at 13.
another pro for learning latin over greek is that chics dig the sound of it more.. it sounds like italian, BIG plus. . so, once you’re in college, it might work out well.
but don’t let that be your reason for learning it. you’ll find tons of gratification in learning the language.
13 certainly doesn’t matter. It’s not early to start learning at all. People here used to start Latin at 8, Greek at 11. I think John Stuart Mill could read Greek fluently by the age of 7 or something terrifying. Hell, people used to be translating Latin poetry into Greek poetry at 16!
But …
13 can be hard without a teacher. One of the things about going through school, college etc is that you “learn how to learn”. You will need explanations from actual humans. This is a good place to get them.
One other point. I am a bit worried when I read you say you are going to “do a lot” of it in one day. That’s not the right approach in the long run. Little and often is much more likely to work long term. Doing all the exercises and keeping your concentration up.
I think as long as you stick with whatever you choose, you won’t regret the choice. I originally wanted to learn Greek but was a bit intimidated by the alphabet and switched to Latin. I’ve come to enjoy latin and a year later I’m now doing both. (though on occasion I’ve found myself accidently trying to translate beginner greek sentences into latin)
One more thing, learning a new language isn’t easy, you should pick a language because you believe learning it will be rewarding. It isn’t like you learn a few basic rules and then you are home free. I am still struggling with latin, but at this point, I’ve put in enough time that I’m willing to continue on (and I have really pretty, color-coded, conjunction & declension charts, )
When I was your age (well maybe a year or two older), I struggled with learning german and just couldn’t get past the fact that I couldn’t simply exchange english words for german ones. Learning a new language is kind of like learning a musical instrument, in the beginning, well, you just don’t sound that great. But in time and with practice you get better and soon it is something you can be proud of.
The point is, learning a new language is a process that takes time and commitment. I think you will be satisfed with either Greek or Latin. The textbooks from this site are good, try downloading one (or all, just to have a look at your choices) and just work a little bit every day.
Thanks everyone.
I just realised doing a lot would never work, to do like 2 or 3 pages a day so it will stick. I got it now.
Does anyone think I should print the book? Its a LOT of pages though 
nostos, though a fair attempt, I did not mean your inversion.
I am not insulting; I am perfectly content here. I maintain that you, little boy, will do nothing. You will end up running away after a few days like the rest of them, but feel little of guilt, since your job as a thirteen year old lad is to run to the sweetie shop with silly little girls, without the depth of latinity not worrying about their inanity. VERZICHTEN SIE NICHT AUFS SPIELEN!

good luck, pjj!
I started studying latin when I was about 11, you’re perfectly capable of studying it as a 13 yo! I wish you the best of luck. 
Do go slowly though, don’t want to discourage yourself by tackling too much material at once.
Latin is easier to learn.
Just to prove you wrong, cause you kind of annoy me, I will learn Latin, k, thanks.
Good luck.
I remember when I mentioned in passing to a teacher of mine that I was considering studying Ancient Greek (at that point I was testing the waters for Ancient Greek), she thought it would be really difficult and that I probably wouldn’t do it (but note that she did not tell me to not tgry). I think that motivated me more than if she had encouraged me.
But yeah, welcome to the club of teenage classicists!
I’ll second Ulpianus’s exhortation. Good luck - and a good work ethic! Both are essential.
-David
Thanks everyone.
I’m going to the library today or tomorrow to get a book on Latin.
And GGG, I think your completely right about what you said.
I think it’s best to ignore him - I suspect his comments are simply aimed at getting a rise out of people.
O te miserum, Episcope! I happen to agree with you, though. It takes a lot for really studying anything on your own. Do you have the resolve to do it, kid? If you really are sure, we’ll help, but only you can make that succeed. I don’t want to hear any whining “But I wanna go see a movie!”
Time to buckle up and hit the trail.
