Pam Slim's new book Escape from Cubicle Nation From Corporate Prisoner to Thriving Entrepreneur has a lot to offer to corporate employees who aren't necessarily looking for an exit, but who are looking for ideas and practical advice on how to thrive within the corporate world. One example is the eye opening exercise Breaking the Grip of Destructive Thoughts from Byron Katie on pages 35 & 36, which provides a simple process for deconstructing doubts and turning around your point of view.
Update: EscapeFromCubicleNation.com appears to be offline just before 10:30 am EDT - I'm sure that Pam is doing everything possible to get this resolved ASAP, but I'm sure she is not happy about this. This is the last thing anyone wants on the day of their book launch.
2nd Update: The problem appears to have been fixed by early this evening.
