What exactly is Parkinson's Law?

Work expands to fill available time. A task estimated at 8 hours fills 8 hours even if completable in 4. Time limit creates natural constraints.

How do I use this to improve productivity?

Estimate realistic time, reduce it by 20-30%, and commit publicly to that deadline. Constraint forces prioritization and reduces perfectionism.

Yes. Impossible deadlines cause stress and low quality. Reduce by 20-30% maximum, not 50%. Experiment to find your productive constraint point.

Yes, but combine with staging. Break large projects into smaller timeboxed milestones rather than single tight deadline for everything.
