I don't mean to discourage, but just to give you a little reality-check before you spend 3 years and a hundred grand pursuing a federal judge position that is highly likely to be nearly impossible for you to get.
Falcon's advice is worth pondering seriously. I too don't like to focus on closed doors, and there are always (or nearly always) second chances. Were you to be the first in your class (even at a 4th-tier law school), a judgeship would indeed become a more realistic opportunity.
Here's a test. (Seriously.) If you've not yet read Planet Law School, read that. It's about as raw a look at law school as there is. Then, if I might, read my own book, Law School: Getting In, Getting Good, Getting the Gold, which provides not nearly as dark a picture but looks seriously as well at the question of whether law school is right for you and, if so, how to go about it. You don't even need to read them in full. Just scan them.
Okay. Do you still have the same thoughts? Do you *love* the idea of law school? Do you see no other career possibility that fills you with an absolute insistance that this is the one for you? Are you willing to go back and read the books, word for word, twice, and implement at least parts of the advice therein?
If you answer in the affirmative, and if you spend a month following through, the answer to your original question is much, much closer to "Yes."
For all, law school is not about effort. Sure, it takes effort, but not nearly as much as most assume. Lots of students burn out long before exams, and nearly everyone does less well than they should because of how they approach law school and preparation for exams. So, to a large degree, the same question should be asked for everyone. After all, even if you don't want to be a judge, being in that realm means that you're in a lot of other good realms too . . . and those will depend, to a large degree, on how well you approached law school. (Note: Not "how much effort you put in," but how *well* you approached it.) The best law students look like athletes--it looks almost easy. (Note 2: It actually is easier, and more fun, the right way.)
