As I've been working on the series "Saying No", I ran across a blog from which I got the Steve Jobs Philosophy for Saying No and the video. If you haven't viewed it yet - definitely worth the view - it's not very long.

In presenting the question for you, I left it in the context in which I found it:
If you need to improve your productivity - then you'll want to check out the book Organizational Strategies for the Overwhelmed - how to manage your time, space, & priorities, to work smart, get results & be happy - Kindle - The Book - Nook - Audio Book - The Seminar
If you are struggling with saying no - I recommend the book: The Power of a Positive No- William Wry
This blog is based on this book. In it are actionable ideas on being a better manager: The 1% Edge - The Workbook - Power Strategies to Increase Your Management Effectiveness
