When I first started creating content, I had the same problem most brokers have.
I'd block time in my calendar, sit down to record, and then have no idea what to say.
The breakthrough came when a coach told me to stop overthinking it and just answer questions.
For my first 50 to 60 videos, I simply answered common questions and shared mistakes I had made along the way. Sometimes the best content is just helping people solve problems they're already asking about.
