As I sit in the shade, I think I should be swimming. While swimming, I think I should be playing in the sand with the kids. While playing in the sand with the kids, I can't help but think I'd rather be sitting in the shade. While sitting in the shade, I think I should really take this opportunity to read a book. But as I'm reading, I'm distracted by the concern that with my nose buried in a book, I'm missing out on the day. So I put the book down and take a deep breath and look out over the beautiful scene. And then I think, really, I should be swimming.
