We have it in our power to begin the world over again.

Nothing about the way things are arranged is fixed by nature. Customs, institutions, the shape of a life, all of it was assembled by people who were no wiser than you, and what was assembled can be assembled differently. The sense that the world is finished is a feeling, not a fact. Power here does not mean control over everything; it means you are not only a passenger.

Pick one arrangement you have been treating as permanent and test whether it actually is. It might be a routine, an agreement, a room. Change one thing about it this week and watch what holds.
