Well, the biggest challenge for me at my last insurance job was basically trying to understand the building concept in America. Being an immigrant, you know, homes were built with different structures, different materials, you know, in many countries outside the United States. So it's, you know, to know the materials being used to build roofs in America, to know the difference between masonry items, building materials, or brick veneer, or frame, you know, and those concepts and how they impact the overall insurance policy was a challenge initially. And although today I've been able to move on from there, you know, and how was I able to resolve that problem? Interestingly, I had to go to a civil engineer friend of mine who was able to break down the entire building process for me, for me to be able to know the differences and the concepts and understand them. And so I was able to see how these various items and concepts impact the insurance needs of my customers, and I was able to find policies that reflect that understanding. So that was a challenge, but I'm happy to say that today I've been able to have that challenge resolved and have a better understanding of the needs of my customers.
