Serenity (n.):

1. the state or quality of being serene, calm, or tranquil.

Maybe it's time that I just sat back and let life come as it will. Because life is too short to stress over. And we are not in control. It is not up to us to decide what happens in the universe. It is only up to us to decide how we're going to react to it.

God,
grant me the serenity to accept the things I cannot change.
