what inspired you to do corporate law ?

Hi I am in 9 grade and I was thinking about going into corporate law. I have done swap meet justice, it is basically where we help people apply for citizenship and help them renew their residency. I wanted to ask you, how did you know you wanted to be a corporate lawyer, what school did you go to, what was your major, and what was job hunting like. was it hard finding a job as a corporate lawyer.
