At first glance this seems like a simple enough topic, its been given the once over in many magazines, but its never been given the degree of consideration I feel it needs. This one topic is everything to your bodybuilding progress. You must have the mental stamina to eat correctly and pass up those tempting Friday night drinking sessions, as well as watching your kids chow down on sugar-loaded sweets that you can have no part of except on certain "special" days.

You must be consistent with your workout, eating, and sleeping schedule to the point you can set the clock by it. This for the average person with low mental stamina seems impossible, but if they looked deep within themselves they would find that there are many things in their lives with which they keep this sort of routine. Excuses only serve to short-circuit your progress, if you want something bad enough, and you have the stamina to achieve it anything is possible.
Now that I've given you an overview let's get down to how mental stamina applies to training. You see guys every day who are dying to get "big" and because they can't do it easily and quickly they want to write it off as drugs.
