Before building a product, validate that the problem is real and worth solving. If you haven't experienced it yourself, talk to potential customers directly instead of guessing what they need.
Sometimes just because we've had a problem, we still need to validate that that is a big enough problem for you to solve in the market. Whereas if you haven't been part of the problem, then you can't make those assumptions. You have to go and learn and be curious and learn from the customer. So very much as part of the validation or customer research process, you have to go to them and learn everything you can and not rely on your own assumptions at all. I hope that answers your question, Emilio.
