One of the most important tasks for a founder is to make sure that the company builds a great product. Until you build a great product, nothing else matters. When really successful startup founders tell the story of their early days its almost always sitting in front of the computer working on their product, or talking to their customers. That's pretty much all the time. They do very little else, and you should be very skeptical if your time allocation is much different. Most other problems that founders are trying to solve, raising money, getting more press, hiring, business development, et cetera, these are significantly easier when you have a great product. Its really important to take care of that first. Step one is to build something that users love. At YC, we tell founders to work on their product, talk to users, exercise, eat and sleep, and very little else. All the other stuff I just mentioned—PR, conferences, recruiting advisers, doing partnerships—you should ignore all of that, and just build a product and get it as good as possible by talking to your users.
