One of the first things you want to do is to keep in mind that at the end of the day you need to build something useful for somebody. So, one of the first tasks is to figure out who is that somebody. Who are you really serving? And what is the job that they're hiring you to do. And looking at it from their perspective will often yield insights that are hidden from the product owner or entrepreneur, if we're purely looking at it from the product-centric perspective. A lot of it is about being at the right place in the right time. While you don't have control over timing, you do have control over two variables, the product and the market.
