On Hacker's news I came across a blog article written by Jess Lee. It was titled Why Startup Founders are Always Unhappy. Her theory was that even though the startup may be growing because of constant bumps along the way founders often feel stressed. I could see how that may be the case. It is easy to miss how far you came when you are looking ahead and thinking about that one thing that you need to do to help your startup do better.
Actually I don't think it's just startup founders who feel stress at their work. Any good knowledge worker will feel stress at the work. Why? Because good ones are always looking for an opportunity to get ahead and have committed themselves to get better at their craft.
