  I'm saying that someone is going to attempt something that pushes them to significant physical limits, they need to have good controls. Feeling like you can do something should be supplement by some understanding. When I teach stretching and movement, I advice my student to only go to the edge of their "comfort zone" at any one point and I only teach certain stretches. It's known that most people's limberness can be gradually increased so that's relatively safe. It's pretty well known (see studies on this page) that most people can't "learn" to go without sleep and I wouldn't advice them to try to do so (the point of the article). And I can believe a few people who in the right place at the right time and brutally push themselves can get rich, rich, rich. That doesn't take away from the point of most people who work with extended years of sleep deprivation screwing themselves up (and this can include a fair fraction of the first group). Sure, push yourself to greatness. I like to push the quality of my activity, not the quantity anyway.
