I think I get it – thank you so much! So my compelling solution would be “I teach you how to get your dream job in sales by building up your self-confidence when speaking English with your partners, not by beating yourself up.” Is that better?
If so, it means that I’ve been too broad up until now and that I need to get to know who I’m talking to. Exciting! I’ll figure out a way to do that. Oh, I know: I can ask my former students and their colleagues!
