Taking a course on what you teach
I used to find it really strange how often I’d see someone taking a course and they’d want help making their own course better (two examples I’ve seen, copywriter needs to improve the landing page of their copywriting course. Handletterer needs to improve thier lettering for their lettering course). Now, I still find it strange but I also think it’s a very smart decision. If you are a coach, you should be constantly improving to make sure you are providing the best advice possible. I do think there is a lower limit there (don’t teach what you are brand new to. And when you do start teaching, perhaps focus on the easiest aspects.) but it’s not completely unreasonable.
