I ask a single question with every course I take: can I list three actionable things I learned from this course? If yes, then the price was probably worth it.

I ask a single question with every course I take: can I list three actionable things I learned from this course? If yes, then the price was probably worth it. I took a Udemy marketing course that regurgitated most of the information I already knew. BUT it included a bit about positioning that I adopted and which landed me more than $10k worth of clients. I paid $20 for it. Good deal I'd say
