Whatever is in our life, but isn't a vital and supportive part and piece of what we are now, exhausts us.
One of my clients was a manager who often wouldn't let herself take bathroom breaks at work. She felt there wasn't enough time. That taking the time would cause her work to suffer. So she held it in. As a result, she was frazzled, anxious, and worn out.
When she saw how the weight of this clutter was affecting her work, her well-being, and her life outside work, she dropped this "time-saving" self-deprivation, and began to go to the bathroom whenever she needed.
Nothing is "sacred" enough to stay in our lives and hurt us. When we discover that something isn't serving us, our word goes. We have the final say.
