If following your passion to a place where there's no pain probably isn't the business, I don't think an entrepreneur can sustain in a place where you don't have passion.

In my view, product/market fit is the most important thing to get right as a startup entrepreneur. There's a variety of ways to do it, but without solving some pain point that the customer gets so excited about they tell their friends, it's really hard in the modern age to get any liftoff.

Spend time with the customers, immersing yourselves, watching. Spend time at their homes. Hear what they say, but most importantly, watch their behaviors as the indication of where the pain is. And then go solve that pain.
