This is something I am sure I will use through the program, but I am afraid if I don't block out a large chunk of time I wont find those precious moments of productivity when I hope for them. Does anyone else have those moments?

This is really good advice. Although, I recently heard that sometimes just scribbling, even non-sense, can actually be beneficial to retaining the information you are hearing. I haven't been able to put it to practice but would love to over the course of this program.
