@ThisKateCreates I see what you're saying, and I do think that this exercise can be difficult. If it doesn't resonate with you, you can just skip it. I think you're taking it in a different way than I did and that is where your difficulty is coming from--which is totally fine. As I said, if you feel the book as a whole is helpful to you but this exercise is just not feeling right, skip it. Or if the book and exercises aren't helping you at all, no need to continue--what would be the point?
To me, this chapter isn't saying that you shouldn't care about anyone else in the world or what they think, about anything, ever. As people who want to create art professionally, making art that people like and respond to is essential. To me, it's about getting really clear about who I need to stay aligned with, both in the work I make but also how I make it and present it. I can't let my art and professional goals eclipse my relationships with those people. I think of the Aesops fable about the man, his son and the donkey who change what they do every time a passerby tells them that what they're doing is wrong, and end up pleasing nobody at all. THAT, to me, is the point. Please your small list of people with the choices you make surrounding your art practice. Some will like and respond to what you make, others won't. But when you're clear on the short list of people its important to please, you won't be chasing after every differing opinion.
Come to think of it, this is important on a personal level for your time and space management, but its important on a business level as well. You need to identify a very specific "target market" to appeal to, and not worry about pleasing people who don't fit that category.
Anyway... I'm sorry you're feeling frustrated here, and as I said, skip it if you feel like it doesn't help you.
