As no current or recent law students have replied thus far (they are all on a beach somewhere), you will have to make do with someone old.
I recommend that you study something which will engage your attention for at least three years, whether that is law or something else. As you may know, you can become a lawyer with a non-law degree.
Studying law requires attention to detail, analytical skills, and the ability to recognise the principle embodied by a legislative instrument or a judicial decision. The study and practice of law require a lot of reading. When I say a lot I mean a lot.
If you are interested in how law is made and develops, then a career in academic law or as a barrister may attract you. If you are more interested in the law as a tool for supporting aspects of human life, you may prefer to train as a solicitor (that interest is also relevant to practice as a barrister). It is sometimes said that barristers are engaged in the practice of law and solicitors are engaged in the business of law, but in fact both do a bit of both. The Bar is closer to the Academy, but every solicitor needs to be a good lawyer and not just a savvy business person.
I suggest that at this stage you ask yourself why you wish to study law. If you have not already read Tom Bingham's The Rule Of Law now is a good time to do so.
