Question re Monday’s cosching call

Hello! I have a question from the 8/13 monday call with Brooke. Its in regard to the marketing professional who said she’d prefer to do more work with nonprofits- I’m curious why Brooke did not encourage her to go all in and create a business where she could contribute in the way she wanted. Why should she keep focusing on a client base if her thoughts are it feels more meaningful to contribute to a different base?
Thank you in advance!!
