I have an unusual hobby: I collect pictures of people I don't know. It started when I was a kid growing up in South Florida, the land of junk stores, garage sales, and flea markets, as a kind of coping mechanism.

It's easy to say you don't care about money when you have plenty of it.

If I never went home, what exactly would I be missing? I pictured my cold cavernous house, my friendless town full of bad memories, the utterly unremarkable life that had been mapped out for me. It had never once occurred to me, I realized, to refuse it.

What I believe when it comes to big things in life, there are no accidents. Everything happens for a reason. You are here for a reason - and it's not to fail and die.

If you must fail ... fail spectacularly!

There was romance in the unknown, but once a place had been discovered and cataloged and mapped, it was diminished, just another dusty fact in a book, sapped of mystery. So maybe it was better to leave a few spots on the map blank. To let the world keep a little of its magic, rather than forcing it to divulge every last secret. Maybe it was better, now and then, to wonder.

But these weren't the kind of monsters that had tentacles and rotting skin, the kind a seven-year-old might be able to wrap his mind around-they were monsters with human faces, in crisp uniforms, marching in lockstep, so banal you don't recognize them for what they are until it's too late.
