Noticed anything particularly interesting about your petrol service cashier, or your Subway sandwich artist, or your librarian? Maybe not. But what if they’re smiling while they provide you with their special service – apparently enjoying tedious and mundane work?

In a flash of realisation, I have determined why I think this is such a pleasing and inspiring occurrence. For it is not that they are smiling at their work. No, it’s much better than that! They smile because they enjoy life, and can see fit to display their enjoyment through all of their circumstances.

Good on you for smiling.
