...I'm not understanding how the first paragraph connects into the second paragraph, or even how the first sentence really connects with the second sentence. These are all seperate issues from what I can tell. Regardless...
1. If your friend wants to lead a healthy, active lifestyle, unless she's in an extreme situation then she has the time to do it, she just isn't making it a priority. The typical 9-5 office worker with a husband/wife and kids "doesn't have time" to exercise, and yet they do have time to veg out on the couch or sit at the computer for 5 hours once they get home from work. If they went straight from work to the gym, spent half an hour a day there, and then came home from work, would it really impede on their "time" so much? For most people, probably not.
2. Everyone has pressure put on them by peers, media, and most significantly themselves, to look and act certain ways, and the exact demands change in every social situations. Once upon a time, people learned etiquette so that they could handle these demands. A word for the wise, it's easier to cope with the demands of the world once you accept that they are the demands of the world, and opt to work with that fact than to resist it.
3. I really don't care much about what fitness models have to say, because it's unlikely I'll hear anything new from them. But I assume that if you have just 10min to work with, that's also what you have set aside for exercise. If I had just 10min per day to train in, I'd pick an exercise, warm it up and work it for 10min. Have a handful of big exercises to work with -- either cardiovascular activities or compound lifts (or both) -- and cycle through the different exercises every time you train. For example, one day you might do squats, the next day you might do push presses, the next day you might do power cleans, the next day you might do bent over rows, the next day you might do a barbell complex, and then rest 2 days and do it all again the next week.
