This fillable document has 5 steps.
The first helps you gather the things to identify patterns in the work you do.
The second helps you get all your potential ideas for a course topic out and start to narrow down to three.
The third helps you make choices.
The fourth has you write descriptions for those three potential courses.
The final step is to share your top pick with potential clients (with guidance on what to ask).
This jumpstart lets you get some initial feedback on early stage ideas without having to do a ton of work before seeing if people are interested in what you want to build. This can help you start the process in a way that feels less overwhelming.
It'll help you decide what flavor of course is right for you, and set you up to work on the course foundations.
