Life isn't all beer and skittles

Life isn't all beer and skittles.

Prov. Life is not pleasurable all the time; you cannot always be having fun. (Skittles is a game like bowling.) I don't really mind going back to work when my vacation is over. Life isn't all beer and skittles, and I enjoy my fun that much more because I have work to compare it to.
