Every time you encounter change, for example: New job, Marriage, Career transition, Promotion, Parenting etc.. It calls for an upgraded version of you. A part of you accepts this change as a necessity, for your growth & well-being. But a part of you resists this, as it feels painful to move outside your comfort zone & thrive to your full potential.
Unless you consciously make effort to integrate these two parts viz being & becoming, you will not be able to function as whole but as fragments. Each fragments run its own script & manifests as interference to your peak performance.
