Ask HN: How to learn sales?
501 by northpoleescape | 144 comments on Hacker News.
First time entrepreneur here. I am creating a product that will solve address a large potential. The more I think about it and read about startup, I am finding that a key to early and often success is Sales. I am been engineer by choice and engineering manager by profession. I have never done sales. I understand you learn by doing similar to driving. I am a bit talkative but sometime I have hard time not getting bogged down by emotions. How do I get started? Can you share books, videos, tutorials, prior recorded sales call references? Where can I learn about metrics to track? Any ideas?
