The reason why I became a lawyer was that I thought that it was an excellent opportunity for me to challenge myself and to grow as a person. Lawyers are nothing more than people with licenses, but once you have that license, you get a voice with which you can speak to those who may not hear you otherwise. I think this is crucial for reaching people and having a positive impact on their lives.
It is not because I think Lawyers have any special privileges that others do not, but more for the fact that we can work together with others to really utilize the law as a tool, not confront it as an obstacle
