Remember that Joseph Pilates called his exercises “Controlology.” The whole concept is being in control of your muscles during the exercises and then incorporating that into daily life–engaging your core for a simple task like standing in line or walking.
We can’t control everything that happens in life, but we can control our reaction to it, and we can control our behavior. Think about extending to concept of what you have control over in life beyond just your muscles. It is very empowering to realize that you have control over your fate (to some degree). You can make choices that make you healthier and happier. It’s up to you. All you need to do is decide to be in control and recognize that while you may not have the power to change everything in life you certainly have say in how you feel about the world around you and what part you will play in it.
