Once you log into the DH Training Vault, click on your INSANE PRODUCTIVITY course from the Library page. This will take you to the Introduction. Then click on the menu in the upper left to access your modules.
Please note that modules are only released 1 week at a time, so when you login for the first time, you will only see the Introduction, the Bonuses and Module 1.
The course is purposely designed so that every week thereafter, a new module will be released into your vault. This gives you the time necessary to take action on what is taught in each lesson before moving on to the next.
