I think he's totally wrong and what davidw said about focus is right on. It's easy to generalize any idea, but most of the time it just leads to mediocrity. Force the expansion out of your mind until you've completely dominated your current target. By then you'll probably see much better ways to expand than this obvious generalization.
Thank you for the input staunch. I def agree with everything you said. I also think its good to set goals for yourself and think well into the future, even though most of your original ideas and plans will end up far from where you had anticipated.
