Lost opportunities, lost possibilities, feelings we can never get back. That's part of what it means to be alive. But inside our heads - at least that's where I imagine it - there's a little room where we store those memories. A room like the stacks in this library. And to understand the workings of our own heart we have to keep on making new reference cards. We have to dust things off every once in awhile, let in fresh air, change the water in the flower vases. In other words, you'll live forever in your own private library.
We yearn for opportunities, we pray for opportunities and we seek for opportunities. The good news is that we meet opportunities. The bad news is that we miss the opportunities only to come to a later realization of missed opportunities.
People regret not achieving enough success in life, they should regret missing many opportunities in life.
People say it's not what happens in your life that matters, it's what you think happened. But this qualification, obviously, did not go far enough. It was quite possible that the central event of your life could be something that didn't happen, or something you thought didn't happen. Otherwise there'd be no need for fiction, there'd only be memoirs and histories...
