Perry Marshall’s book “80/20 Sales & Marketing” is just amazing and you can buy it for 1 penny plus shipping. Instead of paying $22 in the bookstore or $18 on Amazon, you basically get it for $7 bucks.
This is not just another marketing book by the way. The guy who famously cracked the code on Google advertising insists that the 80/20 rule – the adage that 20% of your effort produces 80% of your income – is really the #1 secret to everything. Then he unpacks it like you’ve never seen before anywhere.
I can attest, he takes 80/20 to a level no one else has ever taken it.
