Working at a Biglaw firm: hearing and seeing how much people make (roughly $160k on average their first year out of law school; hearing from accounting and billing how much partners bring in; even the staff do well), having access to clients that literally run the political and financial world, handling resumes (and thinking that I could do this too), seeing that law school is only 3 years long, making connections there, etc.
All of this made me realize how much I want to be a doctor. Somehow, despite all of that money, all of those perks, and the belief that I could succeed in Biglaw, I still wanted to be a doctor. My wanting to be a doctor despite all of the above, made me question my sanity to some degree. How could I want to spend 10 years, essentially making no money or negative digits, to get into a pushed-around occupation IMO (by insurance companies and law makers), when I could go to law school?
I resolved this by running an analysis of myself, my values, my skills, etc. and seeing how that matched up with both occupations. I'm still trying to get into medical school.
My opinion about Biglaw hiring (only read if you're interested): In my opinion, the biggest obstacle to getting into a Biglaw firm, is not knowing how to do it: Interviews take place right after your first year which catches some people off guard, the best candidates will have experience in a Biglaw firm and connections and experience in law and many candidates don't have that, you need a fun personality or at least to really get along with a partner which is just about everyone, you need to look and act right within certain boundaries, and have some impressive EC's. A polished applicant knows this. Where you go to school isn't important or carries very little weight in most cases. Again, I handled resumes. (Some would argue that 1st year grades are the Biggest obstacle, I disagree within certain limits. Some would argue that the system is fixed, and it is to some degree, but not entirely. Some partners know who they want to hire before the hiring process starts, but many don't.)
How important is money IMO: Very. Money can save your life. It can save your family's life. It is what almost every "good cause" is lacking. Money is an essential part of fixing most societal problems. IMO, to say that money doesn't matter is naive, as is saying it's "everything." (I only bring this up because I think my response almost begs the question.)
