Hey Trevor, I'm a fan from Middle East, Iran. So, English is my second language, though I have been studying English for th last 15 years. I've been listening to your podcast and I figured out some probable ways to improve. This is really important to stick to the main topic by shortening the inevitable off topics. They can be cut for later episodes. I believe most of the off topics emerge somewhere down the road. Secondly, I do not feel that I am listening to a conversation, but a monotonous monolog. Since your possess a great knowledge, wrap up the topic from your own perspective, then let the guest exemplify. Just like book chapters, when there is information first, and quizzes and summary at the end. at the end, I want to thank you and all the people who help the HVAC&R community around the world.
