Serving More Clients

I know Brooke says not to do FB ads until you are making 6 figures or something close to that. But I am at a real loss on how to build my business. I have a facebook group and a business page. I go live in my group and on my page. I post on Instagram 5-6 days per week.
I want to start a podcast.

I want to be a fully book coach. That looks like 20 clients (with a waiting list.) But Im struggling to see what else I can do grow my practice but getting more clients. How do I coach myself to create this?
