Those who do NOT teach do not even know how much time it takes to:
a) design a class
b) craft a syllabus
c) read all included readings in the syllabus
d) think about diversity in readings
e) think about pedagogical engagement student-instructor
f) consider in-class activities

g) provide detailed, constructive feedback to each student
h) revise the syllabus as changes are required (often, because life happens or because the class needs readjustment)
i) reconsider inclusion and exclusion of readings as the course progresses
j) grade exams, papers, etc.

k) communicate with and organize teaching assistants (when we are lucky to have one and mine is INCREDIBLE)
l) communicate with and organize guest lectures
m) participate in the guest lectures
n) read materials, think about the narrative of the class
o) prepare lecture slides

And these are JUST the activities that come to mind off the top of my head.

No, kids, the "those who can't do, teach" saying is ABSOLUTELY MORONIC.

Those of us gifted with the ability to translate information and communicate it well in a way that helps learners, DO TEACH.

One last thing: if it's easy for you to understand what I say it's because I HAVE SPENT DECADES PERFECTING THE ART OF TRANSMITTING WHAT I KNOW.

Not because the subject matter is easy.

It's because *I* make it easy for YOU to digest.

And that's an art in and of itself.

I forgot to add:
p) attend instructional workshops and
q) watch instructional videos (both so we can improve our teaching and delivery)
r) engage in mentorship and pastoral care to students who may be falling behind
s) try (and possibly fail) at taking care of ourselves too.

t) deal with teaching at the same time as trying to juggle family and personal life.

Teaching is hard, and it should be valued and paid accordingly.
