How did you get good at sales? Should I just start selling with what little I know, or learn the tech first?
You just start. The only way out is through. You do not need to know a specific platform, tool, or piece of technology, although obviously that helps. The reality is when you sell, you're only ever selling in the space of ideas anyway, so you can sell an idea the same as anybody else with any level of technical skill. What it really is, is putting the words in the right order and understanding, at least to a foundational level, why people make purchasing decisions. Some good books if you want to learn more: Influence by Cialdini, Never Split the Difference by Chris Voss, and Pitch Anything by Oren Klaff — probably my three best sales books out there. If you want a wild card, try When I Say No, I Feel Guilty — written 50-something years ago, it's about how to get over routine social inadequacies around asking for what you want and being assertive. So no, you do not need to know a specific tool stack or piece of technology in order to sell. All you need to do is go out there and sell. Learn the skill of selling and it'll work for whatever product you end up selling.
