Life is a journey sometimes walked in light and sometimes walked in shadow

Grandfather says this: in life there is sadness as well as joy, losing as well as winning, falling as well as standing. I do not say this to make you despair, but to teach you that life is a journey sometimes walked in light and sometimes walked in shadow.
