Five great questions to ask during early customer interviews include: What is the hardest part about doing this thing? When is the last time you encountered this problem? Why was this hard? What have you done to solve this problem? What don’t you love about the solution you already tried?

Find out, 'What, if anything, have you done to solve this problem?' to learn about their attempts at solutions.

Ask, 'Why was this hard?' to gain insights into the challenges users face.

If you're a user of an existing product and find it unsatisfactory, you shouldn't be deterred by its market presence; your experience can lead to a better solution.

Iterate on your solution continuously until it effectively solves a problem; avoid falling in love with your initial product and be open to making necessary changes.

Ask users, 'What is the hardest part about doing this thing?' to uncover their pain points.

When discussing your product with potential users, ask them to identify reasons they might not buy it, which can reveal critical pain points.

In product development, start with proven concepts that users already love. You should not change what works; instead, build upon it to create something better.

It's easy to propose methods for problems, but I want to know if they work in practice and what goes wrong with them.
