Why Did the Weeks After Donovan's Course Launch Go Quiet?

Donovan tells Alex Hillman on Stacking the Bricks that the first week of his course launch brought more signups than he expected. The next couple of weeks were harder. The early adopters had already joined, and the momentum was not there yet, so it went quiet. He got through it by treating week one as the success. People had paid him on the internet and were waiting on a real course. If he sold nothing else that month, he decided, that was still fine. The course started the following Monday, so he stopped staring at the numbers and finished the material.
