Arnold hated the idea that he could be bundled into a group with other, lesser individuals. He stood alone atop the podium and in the public sphere. Everyone knew who he was because he forced himself to be original.
No one matched his physique, and neither will you, but that's not the point. Follow his advice. Be an original. Build your chest and back, and work your ass off to maximize your potential. Only you can control your fate.
Remember to do your cardio! Aim for 1-2 miles 3-5 times per week.
