Why do so many people fail at polyphasic sleeping?

In the past several weeks, I've read countless blogs by people who are logging their polyphasic sleep experiences. It seems like for every one that succeeds, there are nine that fail.

To be certain, adapting to a new sleep schedule like this is difficult. But what, in my opinion, have the harbingers of doom been for these people?

1. Not enough to do. I started this polyphasic experiment because I have an avalanche of to-do's piling up on top of my body. I feel my bones popping and my veins sprouting geysers from the sheer weight of it all. I am entrepreneur at heart, and as such, my brain is always thinking and creating more work for myself. The ones that fail at it almost invariably don't have enough things on their plate to keep them occupied. "Boy, it'd be great to play World of Warcraft an extra six hours a night!" Or, "Think of how many self-help books I could read during the night!" Or, "I could hang out with friends in the day and study at night!" All of these kinds of people will likely fail.
   
   Unless you have a truly full plate and a real hankering for productivity, it's unlikely you'll succeed with a polyphasic sleep routine.
   
   
2. Not a flexible enough schedule. Most of the blogs I've read have been written by high school or college students. While it's feasible to think that you could squeeze in naps during breaks in your school day, it's unlikely you'll be able to maintain it for the long haul. College is one of the craziest, most unpredictable times of your life, and it's not a fertile soil to plant this kind of experiment in. (Usually.)
   
   It also goes without saying that it is difficult to wedge a polyphasic lifestyle into a normal 8 to 5 job. In order for it to work in this scenario, you'd likely need to take a nap right before work, during lunch, and right after work. It is possible, but with this level of rigidity it will be difficult to maintain.
   
   
3. Too much analysis. Some people go overboard with this polyphasic thing to where it becomes the focus instead of the focus being on the benefit. While it's interesting to see ratings like, "Ability to balance fork on my nose: 8", it seems to me that this hyper-analysis is inextricably linked to point 1 above, "Not enough to do."
   
   
4. Lack of support/accountability. I'm slipping this one in, although it doesn't necessarily pertain to the bloggers I've read. It certainly helps to have a support system (wife, friends, etc.) and an accountability system to keep you moving forward with the switch to polyphasic sleep. For instance, I have a wonderful wife who supports me in this, and this blog keeps me accountable to everybody that reads it. I wouldn't want to fail in front of all of you, so I'm not going to. Plain and simple.
