A lot of anxiety right now is amongst people who feel that maybe they missed an opportunity to change their lives. There can be a fear that in order to change one's life, one needs this window of opportunity. The problem with changing now outside of that window is, it seemed like we were kicked outside of time and the usual way of things. How do I connect those two things? No one's ever really given too great of a model of how to do that.
