You're going to kick-ass in your career girlfriend, you're clearly hard-working and have a GPA that many of the lawyers and judges I know who went to the top law schools would die for. Plus, you seem like a kind person.
I went to a top law school, even though I did not have the best grades - they weren't nearly as good as yours. I was a business major, which has absolutely no relevance to what I'm doing now. (I'm a type of a low level judge and hear juvenile criminal matters). I had very good work experience, and many extra-curricular activities. Most of the past 18 years have been spent in the courtroom, but remember not all law consists of litigation. There are transactional lawyers who advise corporations/ businesses, help make deals so they don't have to go to court! One of my friends is an in-house lawyer for a record company; she handled a lot of their contracts and was involved in the deal making the record company made with the artists. The point is, if you aren't the type of person who is gifted in argumentation that's okay - there are many areas of the law where arguing in court isn't necessary.
Even if you want to be a litigator, and don't feel comfortable public speaking that's okay. I heard that the fear of public speaking was ranked higher than death. I think being shot was third, or was it being set on fire....Anyway, I was never a stellar public speaker, not even now, but you get better and better as you do it.
Being a hard-worker is much more important than natural talent - you might need that if you want to be a singer or basketball player perhaps, but not in the law.
I'm not sure how getting a girlfriend, porn and mj will help you in law school. (My own relationship suffered in law school - he was more of a source of distraction; having porn (at least kiddie porn on one's home computer) got one Orange County judge kicked off the bench; and utilizing illegal substances will preclude you from employment with the DA, or U.S. Attorney. You could still work at the public defender's office though).
I'd like to echo thorc954's most wonderful advice: "oh, and another piece of advice, lawyers/law students are generally condescending jerks"
Good luck to you.
