It's crucial to focus on feedback from paying customers, as their insights are more valuable for product improvement than those from non-paying users.

Many founders think they need to offer their product for free to gain users, but it's often better to charge a price to gauge real interest.

You can learn more from customers when they have a product to interact with, rather than just talking to them.

It's crucial to focus on feedback from paying customers rather than friends or acquaintances. Friends may provide feedback, but they might not be your target customers. Instead, you should seek insights from those who are genuinely using your product and are willing to pay for it.

Understanding the difference between users and customers is vital; the user benefits from the product, while the customer pays for it.

You need to find the right users for your product, as feedback from those who don't care about you can be more valuable than that from friends and family.

The best feedback about your product often comes right after you tell users the price, based on their immediate reactions.

Charging for your product shouldn't come from fear of losing customers; it should be based on understanding its value to users.

You only start learning about your users when you put a product in front of them; the goal is to get a product out quickly and talk to initial customers to make it useful for them.
