If you really hate your high school (like I did) "you left my heart empty as a vacant lot" might be a good one.
"My strongest trait is curiosity, I'm just lifting stones, you know,
opening doors. Looking out windows, around corners, up skirts."-Bono
A little paraphrase - "I don't want to be the biggest, just the best."
"Yeah, I dreamed that I saw Dali
With a supermarket trolley "
"I dance much better horizontally than vertically"-Bono
Never trust a man who tells you it's from the heart,
never trust a man smoking a cigar,
never trust a cowboy or a man who wears shades... - Bono
"I know a boy, a boy called trash
Trash can
I know he does all that he can
Wham Bam "

or did you want something more solemn for the occasion?
Seriously, I second "Don't become a monster in order to defeat a monster"
"Of science and the human heart
There is no limit
There is no failure here sweetheart
Just when you quit..."
"One day I'll die
The choice will not be mine
Will it be too late
You can't fight it
I was of a feeling it was out of control
I had the opinion it was out of control"
"You miss too much these days if you stop to think "
"When I was there
I thought the world revolved around me
I was wrong "
Summer Rain lyrics are worth taking a look at. Also Kite, SHFWILF
"It's your future. The only limits are the limits of your imagination.
Dream up the kind of world you want to live in - dream out loud."-Bono
If you can answer ridiculous questions, I'd say go for this little exchange:
BP: What's your favourite method of transportation?
BONO: An angel's back. No, make that blindfolded.
