I'd think you have an issue with your own time management (I do too).
One suggestion that kinda worked for me: try to set a specific time (i.e. 1 hour every day at 9AM) to do X (i.e. watch the MOOC lectures and do the exercises), put an alarm clock, setup your computer to forbid browsing facebook/hn/reddit/youtube in the time period etc.
This way you might be able to make it a habit, which helps you avoiding the procrastinate/procrastinate/forget/ah-crap-too-late trap.
