Ideal Job for my Uncle

Well i will talk about my uncle, hi is a lawyer and is his ideal job because when he was a child he want to be a lawyer, he past 5 years in de university. He really like that kind of job, he defender famous people and importan companies like securitas. He loves the law and defend person it's his best job. I think this career or job it's very difficult because you need to learn al the laws and read really much, it's difficult because you don't know when you take a case if the person you defend has the fault you need to defend, that's what i think.
