Which Ten Are You In?

I remember reading a letter to the editor of the Caltech alumni magazine many years ago.  The writer said that during the first ten years after he graduated, he wished he’d had more training in his major field.  Then during the next ten years, he wished he’d had more training in management.  During the next ten he wished he had more training in business planning.  Then for another ten, he wished he’d learned more about medicine and health.  During the next ten he wished he’d learned more about theology.
