Pocket Man by Scott Jordan is a well written accounting by someone who persevered through all the hurdles to bring a product/dream to market success. The ScotteVest, which I already owned before finding this book, was something that was what was needed as we started carrying around more and more "stuff", mostly electronic.
The perseverance needed over the years is not what many have. It makes us appreciate the work behind things that appear simple. This is oft told saying by folks who after years and years of work become "overnight sensations".
Congrats on a well written and timeless telling and reminder to pursue things you are passionate about.
