What stage are you at? You almost certainly have more time to make this decision than you think. I understand that there is a very real pressure both in the last couple of years of school and at university to have things figured out when it comes to your career, but there are often very good reasons both for not rushing into making a decision if you are unsure, and not rushing into starting the career itself.
There are a lot of relevant factors that go into deciding what career is right for you, and how important those factors are depends on what is important to you. Things like money, working hours, the interest you have in the work itself, career progression, work/life balance, stress and pressure and so on are all things that you might want to take into consideration to one degree or another. The best way to gain insight into those factors is to do work experience and speak with people who do the job, but with most jobs nowadays there are extensive resources online to give you more insight into that.
There are a few broader points to mention though. First, no one career is going to have one experience and one answer to all of those questions. Earnings, to give one example, vary significantly from lawyer to lawyer. So do things like work/life balance. Second, there is no definitive one right answer for you. There are probably several careers that would work for you. Third, when you start a career, you will have so much more flexibility going forwards than you think, either to change career or make significant changes within a career. You're almost never going to be stuck on one path with no absolutely no scope for change. So do bear all of those things in mind, and hopefully that serves to take the pressure off a bit. You're making an important decision here, but it's not one that defines the rest of your life. Not even close. So it's not as important as it feels, and it's not as urgent as it feels either.
