Is this problem a thought?

Hi Brooke,
I’m doing the Podcast workbook, and I’m not sure if this problem I currently have is just a thought, it certainly looks like a circumstance.
The problem I’m having now is about a new art e-course I’m offering, which opened for registration 3 weeks ago, and will start in less than 3 weeks. I’m new to this field but a friend with a more solid fan base is hosting for me so we can get it out to more people. My goal is to have 100 students, but at the moment, we have only 20. So my problem is that I’m far from achieving my goal.
Is this just a thought?
How do I move closer to achieving my goal?
Thank you!
