Concentration becomes easier after distraction stops remaining convenient.

Willpower gets most of the credit for concentration, and it deserves less than it gets. What usually changes is friction. When distraction requires three deliberate steps instead of one reflex, most of the pull disappears before it becomes a decision you have to win.
