Founders get so busy talking, they don't spend any time listening to their customers, missing key insights in the process.

Figure out a hypothetical problem you are trying to solve, and ask questions that explore whether or not your customer has those problems.

You can’t be in the moment if you are constantly thinking about the next moment, so if you want to actually hear your conversation partner, you have to slow down.
