No matter what the career; one has to start at the bottom and learn the career and that takes time. One has to practice, that takes time. Think about your interests and hobbies and how long it took before you actually knew something about them and others respected what you had to say about the subject, etc.?

It is the same with careers/jobs; you may go to school and get a degree in accounting but you don't really become an accountant until you have practiced real world accounting for 10 years. I remember when I turned 21 and was "grown up" but I did not feel grown up until I turned 30; at that age, even my parents recognized that I was grown up?

What would you like to do for that long? It looks like you might have been interning, assistanting, researching in an/area(s) that interested you? I would keep with that as you go to school so you have some practical experience to at least get you a job in the field when you get out, get you enough ahead of the people just going to school, not working in their chosen fields? I think it is a little like teaching, where they make you be a student teacher in order to work as a teacher when you graduate? Any evidence you can show of overall interest in your field, besides just book learning, will help you get a job in that field.
