Marco Arment is the creator of Instapaper (a one-person business) and he worked with David Karp at the very beginning of Tumblr. This blog post I'm posting by Marco is extraordinary. It should provide inspiration to any tech startup anywhere: follow your dreams. He shows how Karp's Tumblr wasn't mere luck, but a lot of hard work and endless hours went into it. You can't help but feel good for David Karp after reading this. It's inspiration. Again: Follow your dreams and work your passion.
