TL;DR How have you negotiated your salary and how best have you employed RP tenets/the 48 Laws of Power to achieve your goal?

Long time lurker and first time poster to TRP. Thanks to RP reading material, I've significantly improved the quality of my days, and it only took a month to do it.

Today we're discussing salary renegotiations and how RP can help make mine go well. The long and short of it is, I love where I work but I am worth more now than I was when I was hired in this time last year. I've applied to and been offered a position with a much larger company. I would be making more than double what I'm making now if I made the move to the larger company. I am going to take their offer to my boss and renegotiate my salary, making light of the valuable contributions I've made to the company and my significantly increased market value over the last year, both due to experience and industry certification that I didn't have before this job.

If you've renegotiated your salary, what approach worked for you? What has the RP mindset contributed to a successful bump in pay?

And for fun, if you've never been in this situation, how will you apply RP to it when you find yourself doing the same thing?

EDIT: The response on this has been huge. Thank you to everyone who contributed to this thread, hopefully others will learn from it as I have. I ultimately didn't bother renegotiating, given that the aftermath problems would not be worth the possible 10% raise. The kind of pay increase I seek can only be achieved through promotion or jumping ship, so those are my only options. Thanks again.
