The present is a comfortable zone.
Many have sacrificed the greatness of their future to the comfort of the present. Between your present and your future is inconvenience. Movement is never convenient. It is stretching that is “stressful.”
But it is that stretch that leads to a spread. The spread may take a toll on you, but it will make you tall in the end. “If the toll will make me tall, then I am eager to go for it.”
