Livin the life...

First of all, before we go any further, we're going to have to find out if you're a true Irish prep, or if you'll have to fake it. So, think about these questions:
a) Does your family live in what's considered a well-off area?
b) Do you have a vast network of friends outside of school?
c) Do your hobbies include sailing, hockey, insert instrument here, acting or singing?
Now, obviously, not everyone's going to answer yes to those questions. If you DIDN'T ANSWER YES, read the rest of this entry. If you DID answer yes, you don't really need to bother.


CONNECTIONS, CONNECTIONS
If you name a private school, I can probably name at least one person I know in that school. Kinda weird, but true. How is this possible? Well, from my vast array of hobbies, of course. You should really know people outside of school---who knows where else they'll pop up? Now, this very neatly brings me onto hobbies...
IT'S ALL IN A NAME Game
Your hobbies are seriously important. You make tons of friends (see above), you get to meet guys (good, seeing as you probably go to an all-girls school), you have skills, and, of course, eventually you'll have an advantage.
If you do acting classes, you'll naturally be fairly good at debating. More of a chance of getting onto the school debating team, so. If you had tennis coaching all winter, you'll beat everyone else come spring. Unless, of course, they're all like you and have been doing the aforementioned hobbies as well. Oh, well. You'll have an advantage eventually. But choose your hobbies carefully. Very carefully. Tennis, fine, as long as you do it in the right club. Apply that principle to all your hobbies, and you're set.
