We can complain about the circumstances that we find ourselves in but that would only be complaining about life itself. We don't have absolute control over our circumstances as we would know from what happens to us daily.
Even a very cursory examination shows that we can't choose our circumstances however we can delude ourselves into believing we can. Our circumstances are a combination of the results of our choices and what life throws at us without our input. Just try stopping the rain.
We can however choose what to do with our circumstances in our response to them in the choice of our actions. We need to remind ourselves from time to time that we end up living our choices which can expand us or contract us.
Our power lies in the ability to make choices with whatever circumstances we find ourselves in. We are never powerless through circumstances but only through our choices.
