I think we confuse the two, stillness and stagnation. I think we get to a point where we're so afraid of choice, we choose not to make any. But that choice, or non-choice, is a catalyst from which a multitude of unasked-for, unapproved choices will be made.
At least by making decisions, we can begin to exert some control over our lives again. Even if they end up not being what we want, we've begun empowering ourselves with our own faith and decided--made the choice--to trust ourselves again. And, over time, that renewed trust will not, cannot, lead us astray.
