A quote from Robert Heinlein's Glory Road that kind of sums up life:
What did I want?
I wanted the hurtling moons of Barsoom. I wanted Storisende and Poictesme, and Holmes shaking me awake to tell me, "The game's afoot!" I wanted to float down the Mississippi on a raft and elude a mob in company with the Duke of Bilgewater and Lost Dauphin.
I wanted Prester John, and Excalibur held by a moon-white arm out of a silent lake. I wanted to sail with Ulysses and with Tros of Samothrace and to eat the lotus in a land that seemed always afternoon. I wanted the feeling of romance and the sense of wonder I had known as a kid. I wanted the world to be the way they had promised me it was going to be, instead of the tawdry, lousy, fouled-up mess it is.
I had had one chance - for ten minutes yesterday afternoon. Helen of Troy, whatever your true name may be - and I had known it - and I had let it slip away. Maybe one chance is all you ever get.
