The point of the article is not only about eating alone. It's about realizing that you probably have lots of small blocks of idle, wasted time during the day: Walking around and talking to co-workers, taking too long to get ready in the morning because you're distracted, etc.

To me, this emphasizes something that I realized at Startup School. This difference between those who find time to make something and those who don't is that the ones who really want it find the time, even if they have a day job, because they simply want it more.

Bravo, great post.
