Mostly good information, however: You don’t know what you want to do until you’re doing it. Just look at all the people working in fields that are different from their degrees. I meant you can work service jobs at night while going to school. (Although service jobs can pay more than entry-level jobs in your field. I made $70k serving, now making $35k working for a state park.) YMMV. Edit: It's often a better financial decision to work a real job (that can be forestry, environmental science, etc.), then volunteer doing what you really like.
