We all walk into darkness.
It is the only uncertainty.
Some wander blindly into the realities obscured in that darkness.
Most carry flashlights to create a certain path that they can walk ahead of them, a path between the realities they're only seeing parts of. lest their flashlights break on the impact.
And some build stars that light up both the walls of reality and the paths between them.
And since they're not holding flashlights anymore, they have both hands free to push against the walls of reality, and/or just play their favorite instrument as they enjoy a walk on a sunny day.
But take note. When one of these people pushes the walls of reality; Those carrying only flashlights are forced to change directions.
