We don’t know the strength of walls until we begin to push on them.

Constraints, borders, limitations — until we test their ability to hold us, their power is absolute.

If we lack the courage, the moxie, even the desperation to learn what is possible … then we risk being held prisoner by paper tigers.

The suggestion is not to run headlong into a solid wall. But what a shame it would be if we didn’t give the walls a little nudge. Just to see.
