"Although there are plenty of people who can fix things, there are not many who will fix things correctly." I wrote this handbook expecting to persuade you to care about the work you perform. I hope that the principles herein will get you focused on perfecting your skills and your standards. The world thinks highly of skilled people like you and me. During the 2020 pandemic, they coined us "essential workers." We help keep the world moving, eating, sleeping, and building capital. This book is my way of straightening things out. My hope is to guide all techs to perform like professionals.
