Hey, grad is fast approaching here in Canada, and I'm in horrendous need of a quotation to be placed under my picture on our school Yearbook.

TL;DR below if the stuff that follows this is irrelevant.

I've searched mainly levels from Halo 2 (in my opinion, having housed the best dialogue in the franchise), as well as Halopedia (halopedia.org, not the other bastardized wiki) for other characters.

I submitted "7here are those who said this day would never come, what have they to say now?", by Halo 2's Truth on the 4 April deadline, and told a friend the next day. He said that it would lead people to believe I wouldn't graduate, which is not the impression I want to leave as my high school career's legacy. Now that's a scary thought! (For the record, his is, "You see a mousetrap, I see free cheese and a fucking challenge.")

So after some searching this weekend, I came up, tentatively, with:
"Every Great Journey begins with a single step. This is our beginning." from the Halo 4 credits. I might end up putting a 7 around there somewhere, I'm infamously well-known to teachers and students for 7ing up their lives, I'll just substitute it for a letter "t".

Just some simple Googling came up with the B.net forums, which some people have already asked for quotations there. The problem I have with some quotations are that some are amazing, yet way too dark and eerie, not fit for graduation.

"Silence fills the empty grave, now that I have gone, but my mind is not at rest for questions linger on."
"If they came to hear me beg, they will be disappointed."

Some are just plain ridiculous:
"I'm a cowardly fool!!!11!"
"Oh, I know what the ladies like."
"To war"
"Bam! said the lady"
"Hey, uh, Captain? Ding-a-ling!"

TL;DR Though the deadline's past, I have someone who runs yearbook and he'll slip in a quotation revising as an inside job. Though now I ask if anyone has any great, inspiration, yearbook-fitting, Halo-related quotation they'd like to share, and for me to subsequently use?

"One final effort is all that remains", but I have confidence for the weeks that follow.

Thank you, everyone, really.
