You can do both.   Check out your local community college.   They are always looking for teachers in their so-called “adjunct faculty” to teach evening courses.   I did this for many years, and let me tell you ... whereas ex-high school kids who don’t yet know what they want to be when they grow up are a little bit exasperating, adults (and it is entirely possible that one or more of your students have PhD’s ...) will keep you on your toes!   Fair warning:   this is serious college stuff.   Try to bluff dem cats, and you are $DEAD.BEEF.   The adults who go to community colleges have, likely as not, already been through “the undergraduate scene” and they are not really in it for the certificate.   The student loans were paid off years ago:   they are paying money for this, out of their own pocket.   They want information, and they want access to industry experience.

(Loved it.   Still do.   It just isn’t very often that you do something that makes you realize, “hey, this thing I’m doing right now really matters ...”)
