This is pretty over the top and I'm thinking this was possibly said with a bit of satire, but whatever the case, this advice is good for somebody whose got Mr. Olympia coming up in say, oh, a couple of months.
With the motherload of information that is currently available through this site and the internet, it sometimes seems as if we have at our fingertips the blueprint of what will further and what will harm our goals in relation to fitness and nutrition. So therefore, it is easy to fall down the slippery slope of clean food all the time, no alcohol, nothing less than 8 hours of sleep, etc.
However, I think it is safe to say that most people, at some point or another, got into this whole deal because they wanted to feel better about themselves and be able to have a better quality of life in general. However ,when it gets to the point of feeling like you can't kick a few back at a friends wedding due to it being against the whole bodybuilding philosophy, I think that things might be taking the turn toward obsession, (with no clear goal, i.e., not a pro) rather than a hobby that you incorporate in order to have an overall well rounded life.
