Opportunity comes ever so stealthily, like a boy who is hiding a bouquet of flowers behind his back to surprise his date on the date of the high school prom. The coming (comings - OK?) of it is ever slow but the going (goings - OK?) is ever so obvious. Once you missed it, you knew it right away. This unexpected nature of its coming is what calls for ever-readiness if you want to catch it when it comes. Many people seem to have stress the importance of being ready for those sudden moments when opportunity present itself. If you are not ready at the moment of its showing its face, you will most likely to miss (to have missed?) it and see (have seen?) it pass you by. So be ready for those moments of opportunity to catch and hold onto it ever so firmly to make it your own. Good luck to you all.
