Intuition is a powerful and primal force that relates closely to the concept of no thought.
Something is intuitive if it unfolds in a natural, internalized way that feels right. Intuition is that internal voice that is often quiet, or not listened to, but is usually right. When a designer listens for the correct solution, the answer that comes is often not something that is immediately obvious.
Get good at listening to your intuitions. You know more than you think you do. Your heart knows more than you think it does.
Is there any way to make my solution more intuitive to my customer? What are they expecting? What feels like the best solution to me? Am I there yet? Does it feel right?
