If the field of what you are teaching is related to your career the transition should be very doable.
There is much value in being a “subject matter expert” SME.
‘Sobriety leads us to humility. Humility is also important, I’ve learned, in teaching.
I was advised, early on, to not BS my students.
If unfamiliar with a concept or topic or item of discussion, embrace that as a chance to learn together, or, tell them you’ll look it up and get back to them.
You’ll do well, in sure.
Enjoy!
