Y Combinator's motto is to 'make something people want.' It's crucial to identify the most important problem right now and determine how you will solve it.

The mantra of Y Combinator is to build something people want, and we learned to constantly improve our product based on customer feedback.

The lesson from startups is to focus on creating something people want first, even if it involves non-scalable methods. Once you have demand, you can then work on scaling solutions.

You should focus on creating something that people want rather than just trying to start a startup; this mindset is crucial for success.

The advice I would give to new YC founders is to focus on making something people want and avoid distractions that don't impact your bottom line.

It's essential for founders to focus on creating something that people genuinely want, rather than getting sidetracked by other operational challenges.

At Y Combinator, we advise founders to focus on creating a product that 100 people love rather than something that 1 million people merely like, as those 100 passionate users can become your viral sales force.

The most important lesson I've learned is that it's really hard to decide to start a company before you understand what you want to do.
