Teaching is quite honestly a terrible profession at this time.
Since we cannot admit kids are unequal, you will be given morons and even retarded kids and expected to educate them.
Your course materials are closely mandated by state law, and highly politicized one or both ways (left and right).
Children can stab you can get counseling; if you fight back, even in self-defense, expect a year suspension.
Many of the children will distrust or hate you because of your race or background.
Because it's such a mess, the education profession has been abandoned to mostly insane bureaucrats who blithely enforce unrealistic rules and tend to shoot down any rising stars. They like conformity; it's safe.
Teaching used to be an honorable profession. If you are lucky enough to get into a private school, you may still have that experience. But then you'll be teaching elite kids from wealthy backgrounds.
If anyone comes up to you with idealistic blather about teaching, be very cynical.
