Being an attorney works like you say. You can work 80 hours a week, have little time to do things outside of work, but make big bucks. Or you can work 40 hours a week, have a great quality of life outside of work, but not make as much money.
The one great thing about being an attorney is that you have a HUGE network of people that you meet throughout your career. I have know a lot of attorney’s that have left the practice of law to enter into joint ventures with other business people and have done great.
If you have a law degree and a good business skills the sky is the limit.
