[A] society is defined by its boundaries; a culture is defined by its horizons. […] A horizon is a phenomenon of vision. One cannot look at the horizon; it is simply the point beyond which we cannot see.*
(James Carse)

When it’s your turn, it’s your turn. You own it. Your choice. Your freedom. Your responsibility.**
(Seth Godin)

Boundaries are vertical, horizons are horizontal.

Boundaries exist because of some resistance on the other side of the line, horizons are open, we can never reach them

The future will be more about horizons than boundaries, if we want it to be.
