Everything powerful in the human spirit can be seen as a foundation. Maintaining, and better-still building-upon and strengthening, those important foundations, takes constant care, nurturing, and attention. Self confidence begins with a foundation of respect and needs constant attention and care to maintain and build one's unique self. Similarly, strong, loving relationships need continual nurturing and respect to honor that unique someone in your life.
Why would our bodies be any different? We need to apply these same principles to our unique physical bodies as well. Some readers may laugh at this statement but we truly have to respect, admire and attend to our physique before it can develop in the powerful way we want it to. Watching TV, reading the newspaper, or talking to others while working out, (specifically while strength training) does not develop this foundation. Yes, it makes the workout pass by more quickly and distracts you from something you may not absolutely feel like doing at that moment, but the truth is why do it if you're not going to do it properly?
