I no longer have the reference, but the key to getting larger tasks done is to break them down into smaller tasks and then schedule the smaller tasks. So "Write syllabus for new course" is useless to me, but "review book," "seek other books," "seek articles," "review book1," "review book2," "review article1" (etc), "develop assignments" all get plugged in to my schedule and the syllabus gets done. "Break down and schedule JobX" is also a mindable task.
