I’ve been a fan of Tim Ferriss since I came across his “4 Hour Work Week” book years ago. I recently got his latest book “Tools Of Titans”

On page 375,  From Peter’s Laws, Law 26 – “IF YOU CAN’T MEASURE IT, YOU CAN’T IMPROVE IT”

Indeed! I am forced to adopt this quote as the mantra for audiomeasurements.com

I strongly recommend this book!
