We are freaks for having discipline, aiming at lofty goals and changing our lives in order to achieve them. The average person is perfectly happy with the status quo and finding the minimum required in life. They want to hear and see people like them as it helps justify their current state of existence.
All of us here have taken the hard road to health. We don't buy into the meal-replacement (starvation) regimes or 15 minutes exercise. We endure our 3-weekly sessions of calculated, self-inflicted suffering. We even take pleasure from our pain, for we know the benefit that will arise.
The best we can hope for is that those around experience a shock so great that they too are spurred into action, in the right direction, before it's too late.
To quote Gandhi:
First they ignore you... Then they mock you... Then they fight you... Then you win.
At which stage are you?
