Well I don't think the article is speaking about infinite energy here. If you are truly tired, you will need sleep but some people claim needing a break every 10-15 minutes of studying. That's the kind of stuff the article seems to talk about. I know I have that problem, I'll loose focus easily. I can work out 5-6 lines of code and start drifting off. But when things are working out good, I can focus on it for hours just spurting out code. I love those moments. The point is, you still need sleep but procrastinating on HN every 20 minutes is a bad thing (Talking to myself here ;p)
