I'm no dispassionate reviewer.
I'm a fan.
Bought my first Godin book in '96, The Guerrilla Marketer's Handbook, co-written with the original Guerrilla Marketer, Jay Conrad Levinson.
These are only three sentences that show why you should buy Seth Godin's Linchpin:
1) "It's OK if i get fired because I'll have demonstrated my value to the marketplace. IF THE RULES ARE THE ONLY THING BETWEEN ME AND BECOMING INDISPENSABLE, I DON'T NEED THE RULES." (Emphasis mine.)
2) "Emotional labor changes the recipient, and we care about that. That's why emotional labor is so much more valuable than physical labor."
3) "Thinking About Your Choice: And it is a choice...to buy into the fear and the system, or to chart your own path and create value as you do. It's your job to figure how to chart the path, because charting the path is the point."
OK, OK. So these are three excerpts, not sentences.
My point is -- Seth Godin gets it, gets it, gets it.
In Linchpin, he gives it to you.
It's a gift.
Pick it up.
