Serenity

When I say Serenity what comes to your mind?

Is it the film? I know it is for a large number of my friends.

Or perhaps the idea of a perfect spa day get away? We can dream right.

Or is it the prayer? It is for me and for many others I know.
And for us, here it is:

God grant me the serenity
to accept the things I cannot change;
courage to change the things I can;
and wisdom to know the difference.
