The gift of going through a phase is that it will pass and you will come out the other side.
For example, we may go through a phase of needing to learn how to say no, as part of learning to set boundaries and take care of ourselves. During this time, we might say no to just about everything, as a way of practicing and exploring this ability. Like a child who learns a new word, we want to try out this new avenue of expression and empowerment as much as we can because it is new and exciting for us and we want to explore it fully. In this way, we are mastering a new skill, and eventually, as we integrate it into our overall identity, it will resume its position as one part of our balanced life.
In this process, we are overcompensating for a quality that was suppressed in our life, and the swinging of the pendulum from under-use to overuse serves to bring that quality into balance. Understanding what's happening is a useful tool that helps us to be patient with the process. In the end, the pendulum settles comfortably in the center, restoring balance inside and out.
