While everybody else focused on the rain drops,
she focused on the distance between rain drops that
had touched the Earth and
rain drops that were yet to touch the Earth.
She didn't focus on what she could not change.
She did not focus on the past.
She focused on the possibilities held by the future;
she focused on what she could change,
which is why

She never focused on the raindrops;
she focused on the distance between them.
