A lot of people don’t know how to negotiate a job offer, especially if they were going to accept it no matter what. Use this technique to get an increase in the offer, which will compound every year since raises are almost always percentages or “bump up to the nearest big number”. Doing this at my last salary negotiation has probably payed off in the range of tens of thousands of dollars over several years.

Allow me to present Gavin's Super Simple Job Offer Negotiation Strategy for People Who Hate Negotiation, Don’t Have Any Other Offers, and Are Going To Take the Job No Matter What:

Call 1: They call you to make the offer

Them: We think you rock and would like to hire you. We can offer you $X.
You: Great, that's really exciting (etc). I'd like to take a day to think it over.

	# Type the password last time to apply the new mode and forget it for any console task for ages
	# Use the rollback to restore password protection
