Having an entire product rest on your shoulders sucks and emotionally drains you rather quickly. In my case it was a startup with a technology I created on the side that became the main business and eventually became the sole earner for a company whose other business had already been dwindling. At the time there were maybe half a dozen people in the country that even worked in this particular niche. If I left the company it would likely go down, and the CEO kept telling me how many people would lose work if I left. And the pressure and responsibility kept growing and growing. And the sales people, who made up half of the staff, kept getting more and more antagonistic, as I couldn't meet their constantly larger expectations, which were often technically impossible (like sci-fi movie level). This situation lasted for over a year, culminating in a huge blowout between the CEO and I when I left. I became a Rick real fast. I still feel like shit for being a Rick, and it's taken years for me to move that experience out of my "work baggage".
