There's no denying the work ethic of those dieting/training to the point that they're "able" to compete; however, there's a huge difference between the character of those who "suffer" and those who "sacrifice."
Among those in the physique world are those who don't seem to enjoy anything. Not dieting. Not training. All you hear is the endless complaining of how tired, hungry, bitchy, anti-social, blah blah they've become. They're imprisoned by what the pursuit is doing TO them. And you'll also witness the sour grapes of those who don't place well when they feel that because they "worked their asses off" the hardest and suffered the most, they should be getting the trophy.
The mindset my Coach has dealt with among physique competitors (and yo-yo dieters, anorexics, bigorexics I'm assuming) is bizarre, and I'm guessing it's not as common among the general population or even among other athletes as it is in the bodybuilding/fitness world.
The self-discipline you see among those who rise above matyr status is something I used to refer to as "having one foot in Heaven." I know that's a bit too religious for some, but this was an observation I made in childhood, and I didn't know any other way to describe what I could sense in these people. They just seemed above the pettiness and struggles in which so many of us spend our lives.
I don't need to examine my work ethic. I need to examine my character. I am always watching, and I've too long been cheating myself, half-assing the self-discipline I've sought for so long.
There's more to the equation than work. There's the whole notion of sacrifice. Sacrifice, willingly and joyfully made--not choosing to suffer--is where I need to change my attitude. For me it goes back to the infantile ego. Children need rules, boundaries, limitations to keep their infantile egos in check. Many adults never get beyond needing these external limitations.
The sacrifice needs to be made for its own sake. Nothing more, nothing less. Why? Not to impress some panel of judges or win a trophy or get a contract, but because it is right and true to master the infantile ego and allow your true Self to transcend.
