College professors are cloistered in study halls, labs, and libraries and never enter the real world or get any sunlight. They also got their teaching limited sections and have limited interaction with society.

High School teachers are on the front lines and in the trenches. Fighting with students, teaching 4-5 classes a day, fighting with parents during student conferences, and staying up all night preparing lessons and grading papers.

Teaching High School can be brutal. Many students don't want to be there but they have little to no choice. By the time they make it to college, they usually want to be there or they just leave. Kids and teens are all about drama and often drag their teachers into their world and home situations. College professors and lecturers are usually able to avoid the drama.

Teaching High School and Elementary School is tough. Teaching Jr. High is insanity. Teaching at a college or university can have drama, but they're adults for the most part, not kids, and therefore should and can be held responsible for their actions.

You can also receive tenure at a college or university. Sure, publishing and research is crazy to coordinate with teaching, but so many professors schlock much of it off on their overworked T.A.s to care. Grants are tough to get, publishing is hard, but you have a lot of autonomy. They don't have to teach Common Core and whatever the State tells them to teach, so they have a lot more flexibility, unless they have a hardline department vision to follow.

High School teachers are easily fired and replaced. College and University professors, not so much.

Just a few things to think about.
