The thing that makes me naturally good at my job is my communication skills. Which is also my essential skill for business. Not only the way I articulate the issues and solutions to my clients, but the the way I keep up with them and keep them updated throughout the build process. And immediately address any problems or concerns as whey arise. 
Coming from a commercial fishing background, roofing definitely found me, and I was surprised at how well it fit me and my personality. Three years in and no looking back!
