The people and the freedom to study in a number of different areas.
UNL gave me a foundation of both content knowledge and basic teaching skills that I could rely on as I navigated those first years as a teacher.
Don't limit yourself to 1 field of study. You, most likely, will never have another opportunity to learn from experts in so many fields. The education available to you is for more than preparing for a career; you have the chance to be educated, not just trained.
