I spend a lot of time convincing (or trying to convince) entrepreneurs & founders that they are more important to their business than their idea or product. Starting out, it seems most people want to believe all they need to do is have a great idea or build a pretty product and they'll be successful. Ultimately, what matters most are the people behind the opportunity. I believe that if you put the right people, in a big enough market, with enough runway, they'll figure out how to make a successful company. Unfortunately, those are a lot of big ifs.
From the time we're born, we're told what to do, how to do it and when to move on to the next task. For those that choose to start their own companies, very little that we've been taught, learned or done in life teaches us how to manage the vastness of figuring out what is most important in your company. On any given day, everything is important and everything needs to be done. For those with very early stage startups, sometimes you're the only one around, available or willing to work for free.
