You are thinking about this wrong. You are thinking only about the amount of income. You need to think/consider what you enjoy doing. I suggest that you take a "vocational test" - this isn't a real test, but rather asks you about your skills, interests, likes, and dislikes. THIS is the best way to choose a career - THIS can save you a lot of time and money.
By the way, jobs in the field of Law are drying up FAST!! This is NOT a good field to invest time/money in!!! Many reasons. THE main reason?.........We simply have WAY TOO MANY Attorneys/Lawyers - we have a GLUT!!!
So even IF you finish law school, you probably won't be able to find a job when you are done. Now the law schools know this> the market/economy is SATURATED - but they won't tell you the truth. The law schools continue to churn out law graduates. A law student is easy money for a law school - a law school has to make very little investment in a law student, compared to other areas of study.
Now if you want a JOB when you are done with your studies, consider and look into the field of HEALTHCARE!< THIS is where the jobs are! and scholarships!
Good luck.
