1) Dont' go to law school just because you're not really sure what else to do. It's too expensive for that, and debt is a big, bad thing that you need to think hard and carefully about before you load yourself up with it.
2) The legal world attracts risk-averse, heirarchical, highly competitive types. They frame a lot of the conversations about the profession. Therefore, a lot of default expectations about where you should go to law school, what you should do while you're there (e.g. law review), and what kind of job you should knock yourself out to get after school, have to do not with the substance of the activity, not with whether it fits your personality, interests, or skills, but on the perceived "prestige" and exclusivity of the choice. I maintain that this is a bad way to make decisions about your life.
3) Law school is really fun. I loved it. It's hard, in a good way. It can help you think very precisely. You'll understand our government better than you ever did, and you'll come away with great respect for the system we've built. (And you'll probably mourn harder the damage we're doing to due process with bills like this.) Learning to read statutes and legal language is useful: it means nobody can bully you. You can parse out problems in a great way. But these skills are not necessary to living a happy and productive life. Incurring a great deal of debt to get them is not a good idea, unless you are certain that you can pay off that debt without doing something that you hate.
4) Most lawyers at big law firms hate it, wouldn't recommend it for their children, and wouldn't go to law school if they had it to do over again. Pay attention to that. Read this article. It is these same people who mark this career path as extremely prestigious. But they wouldn't do it again. One speculates whether "prestige" is something that unhappy people use to prop up decisions that they regret.
5) The happy lawyers that I know tend to be those in small or solo practices, those who are public defenders or prosecutors and who feel a strong sense of mission to their work. The business model of the billable hour and the culture at large law firms makes it hard to have a balanced life, and lawyers at big firms are often unhappy. This is consistent with happiness research, that suggests that people who spend their time doing things that connect them to other people, and that give them a concrete sense of helping other people and being part of a larger community, are more content in their lives. Above basic subsistence levels, neither money nor "prestige" contributes to a sense of well-being. We are wired to constantly chase things that won't make us feel better. To be content, we need to recognize these tendencies, and not jump on the hamster wheel and try to run faster.
6) I think the legal profession is often dishonest to aspiring lawyers, in what we fail to tell them. The most shameful way is ignoring the impact of debt on the freedom of young people to shape their own destinies. You have a lot fewer options if you need to service $150,000 of debt than if you don't have any, or even if you only have $40,000. The platitudes about a law degree "opening lots of doors" is incomplete if it doesn't acknowledge all the doors that an extraordinary debt load closes.
