I would have to agree with what others have said. First, it is no guarantee to come out of law school with a job. I got lucky and stayed with the firm I clerked for prior to graduation, which is how many secure jobs these days. Second, the majority of lawyers work a lot of hours, at least your first few years. I have been practicing a couple of years now and still put in long hours. Luckily, I do have time to brew consistently but do not believe that working in/owning a brewery at the same time would be possible.
Finally, as was stated previously, if you are using law school as a means to an end, then I would recommend doing something else. The whole idea that lawyers make tons of money is not exactly a true representation. Here in FL, I know lawyers who had to move back in with their parents because of the substantial student loans and not being able to afford to live on their own.
Ultimately, it is your decision. I would recommend you do what you think is best, but don't make an impulse decision.
