The thing that scares the Archer more than the Boogeyman is the possibility of losing independence. Freedom is essential to Sag’s view of the world. Without unhindered movement or decision making, life is literally not worth living.
Fixed lifestyles are not for Sagittarius natives. They need to be the sole owners of their lives, free to choose what to do and where to go. Archers won’t tolerate living in a trap of a routine; they will do whatever it takes to achieve a 100% level of freedom.
