Thought of the Day - Student Syndrome

“Parkinson’s law dictates that a task will swell in (perceived) importance and complexity in relation to the time allotted for its completion.”

Sounds a lot like the 'student syndrome' discussed in Critical Chain. My question is how do you artificially shrink the time you allocate to tasks; do you postpone them until just before the shrunk deadline or do you do them now with a set end time ... Both have motivational issues and it sounds like the Start Early Vs Start Late debate in project management.

Therefore the question becomes; how do you determine the Critical Chain in your life so that it doesn't matter when you start the non-critical tasks?
