I've long been intrigued by what a sabbatical affords you in terms of opening up a way of making big changes in your life. Not surprisingly, you can find some books on personal sabbaticals to get guidance on how to structure a sabbatical (You can also get a sabbatical coach (e.g., Coaching Services) but you should be able to get a lot out of reading a book and spend $600/month!). Some interesting looking books on the topic include:

• Unplugged: How to Disconnect from the Rat Race, Have an Existential Crisis, and Find Meaning and Fulfillment (Culture Tools): Nancy Whitney-Reiter: Books:
• Power Sabbatical: The Break That Makes a Difference: Robert Levine: Books
• Time Off From Work: Using Sabbaticals To Enhance Your Life While Keeping Your Career On Track: Lisa Rogak: Books
• Escape 101: The Four Secrets to Taking a Sabbatical or Career Break Without Losing Your Money or Your Mind: Dan Clements, Tara Gignac: Books
