Follow through or lack there of is a common problem with self paced courses. We don't commit the time to our calendar and then forget to do it. It's more often than no there is a loss of motivation. They why we are doing this and what we ultimately hope to get from it is lost in our day to day existence.
My suggestion is you stay your focus on completing the goal. Make a plan and use the Paraliminals as needed. You may want to take another goal through the Accelerator while you keep working on this one. I think we need to give ourselves a break when getting into a new habit it takes 21 to 30 days. And while we commit to our desire to complete a course we get side tracked. The best way not to is to plan for the time when you will do the course each day for the next week and then put a time in the calendar to schedule the next weeks effort.
Congratulations on completing the course once through. It is an achievement even if the 40 days were spaced out
