The knowledge is everywhere. The finished product is not.
You have probably saved the videos, bookmarked the threads and started a course or two. You know a lot about creating digital products. You just have not made one yet.
That is not a motivation problem. Learning feels like progress, so it is easy to keep learning. What is missing is a place where you stop reading and start building: a clear order of work, and a tool in your hand at every step.
That is what The Product Workbench is. It is built around doing. You pick one product idea on the first day and work on it until it is finished, tested, priced and ready to sell.
