I am a lawyer and have been one for 23 yrs. There are good and bad parts of the profession, and if it helps I will share them.
Becoming a lawyer takes a 4 yr college degree and then three years of law school (or 3-4 if you go nights Year round instead of days only 9 months a year). Private schools cost more than public schools so if cost is an object - and in my opinion it should be - go to a public law school. In most cases the public law schools are just as good or better than private ones and they cost a fraction of what private schools do. In my state (Florida) the University of Florida and Florida State are the best law schools and their Bar pass rates are as high or higher than the other schools. They are well run, their alumni love the school and support it w/ scholarship dollars and job connections for graduates so consider a state school. If possible, decide what state you think you want to live in when you get out and practice b/c the law schools are geared a lot more to your state's laws (since 90% of your practice will likely be in State, rather than Federal courts) so it is a huge plus to have gone to a law school in the state where you want to stay and practice. It's been a long time since I was in law school and I am sure tuition is not cheap, but no graduate program is and if you go to a state/public school, you will be fine. MAKE SURE YOUR SCHOOL IS ABA APPROVED. Some private law schools are not and this can make it hard or impossible to sit for a Bar exam. About 99.5% of law schools are ABA approved but check to be sure.
Once you have a law degree, you can do anything w/ it and are not cornered into doing criminal work w/ alleged rapists, etc. if that isn't your thing. If you like criminal law but don't want to represent people accused of crimes, become a prosecutor. Other options are civil lawyers (I am one) and representing people who are either suing folks or getting sued (I represent people who get sued for causing accidents, etc). Other lawyers I know do financial planning, wills, estates, family law, adoptions, work for non-profits, grant writing, politics, analyzing laws for companies, mergers & acquisitions, civil rights, teaching, running hospitals and companies - and about 1,000 other things.
I like practicing law. It teaches you to analyze and that opens lots of doors so that you can do what interests you. Since I got out, a lot has changed financially in law and salaries in general fields like litigation have come down some though other specialties (like tax law,etc) remain in very high demand and command big salaries. Chances are you won't get filthy rich but that you can make a decent living doing it if you are honest and care about your clients.
The bad side: sometimes your clients don't understand and appreciate how hard it is to do your job. The solution is just educating them if you want to.
All in all it's still a good field. Don't write it off b/c of a few comments made by people not in the field. If you are interested, considering interning for the court system, a law firm or public defender or prosecutor's office. Find out if you like it before you make a commitment to 3 yrs of law school. I think you will like it. Good luck/
