What I wasn't really aware of was how difficult it would be to land a job, and you're not going to love what you do right away. It helps to have connections and successful people to talk to. Some of my mentors are people who have very little knowledge about environmental science, and in some ways that's better than just talking to people in your field. I had a very focused idea of what I wanted to do after graduating, but I've learned since then you have to be more open to different opportunities.
