I met another woman at a local community center who was ready to start exercising. Seems part of her foot had be amputated because she didn't know she was diabetic until a small blister on her foot had turned gangrene. Can you say, "Wake up call!"?
If you think your life is too busy to exercise, then you're just too busy. Our lives are on on the fast track, but if we stop to think about it; fast track to where? We can be pulled in so many directions that we end up off the track towards our true destination/goals. Prioritize what's important and ditch the rest, or at least limit it. Sure, Facebook is fun but it's not imperative that you post the latest about your pickled asparagus, or that you're tired and going to bed, much less read about it.
The first step is identifying what you do with your time. Then prioritizing. If you want to be active you'll figure out how to make it happen. Good luck!
