I really enjoyed this book. It's about improving one's productivity. Some of the knowledge is common sense while some was new to me and I think very useful.

The main points were:
*Do your most difficult, least-liked tasks first.
*Keep doing them until finished.
*For larger tasks, break them into small chunks.
*Prioritize your tasks.
*If you can avoid doing a task, avoid doing it.
*Develop a sense of urgency.
*Don't multitask.

It's an easy read and also comes as an audio book.
