Whether or not it is "worth" pursuing a career in law depends on what you want to get out of it. Many people go in to careers for the potential salary that they may make. Realistically getting a graduate degree will higher your possible earning potential, but not necessarily. If your goal is to practice a particular field of law (for example criminal law or family law), law school is certainly the right choice. If you want to help people or make a difference in a particular area of law, you may not need to go to law school. There are many other types of jobs in the legal profession that do not require a law degree. Being a lawyer allows you to handle clients on your own, argue before judges in court, and represent people/organizations in a variety of situations. Law school is a 3 year program, it is expensive, and in my opinion challenging. In my experience, having a law degree has allowed me to not only practice law, but also mentor and teach which has been very rewarding. Best of luck!
Cons: long hours, deadlines, high stress
Consider the amount and cost of school required. College is 4 years, and law school is 3 years. Even the review courses for the admissions test and the Bar exam are expensive.
There is a huge variety in law just as there are types of medical practices for doctors. Ask yourself what you are good at because there is probably a kind of law where you can use your strengths.
The final answer is it is a good job if you enjoy it, and it is worth a lot of work to you.
