It might sound cool to be a spy, or to be involved in some sort of intelligence stuff, but then you hear about some spies of ours getting caught by Iran and Hezballah. When a CIA official says "we'll likely never see these guys again," that's when the reality of the intelligence business should set in.
It really is a shitty, thankless field to work in. Sure you get to tell people that you can't talk about what you do, and then chuckle at them for their inevitable probing questions as though they think they're crack interrogators who are going to trick you into revealing what you know, but that's not enough to make it not suck.
I know what it's like. In the Navy I was a cryptologist. I only spent three years as a cryptologist, so I didn't have the chance to get into any of the seriously crazy shit, but three years is enough to know how much it sucks.
For starters, there's that whole thing where you can never tell anyone anything, ever. That sounds cool at first, but after a while it gets frustrating. I did some fairly cool shit in my time. I was really good at what I did, and I wish that I could share my success stories with the people I care about. But the only people that knew just how good I was and the great things I did are those who worked with me and were cleared to know that sort of stuff. I haven't seen them in years, and even if I did see them it's not like we could talk about it out in the open.
It actually affected my marriage a bit. My ex-wife didn't like the fact that I couldn't come home and talk about work other than whenever we had to paint something. She didn't appreciate the idea that there was a part of my life that she'd never be privvy to. You see in the movies where spies' wives get all upset about that sort of thing, and I always discounted that as silly. "This can't be realistic. Of course their wives would understand." Well, not all of those wives understand, I guess.
And aside from how it affects your personal life, there's the nature of the work itself. Intelligence is not the place for people who enjoy discovering concrete answers to their burning questions. Much of the job revolves around guess work. Try this little exercise. Observe one person for like a month or so, and after that month try to predict their daily schedule for the next month.
Sounds easy, right? Well, it's not that easy. The person might call in sick for work one day. He might stay in for lunch rather than going out. He might go out with his friends and be too hungover to get to work on time the following day. Then, after you realize that there are a million variables you have to take into account in your observations and predictions, throw five more people into the mix. Try to predict what six people are going to do every day for the next month.
As if that's not hard enough, let them in on the little exercise, and tell them to willfully try to throw you off their scent to make them more unpredictable. Still easy?
Intelligence involves a *lot* of guess work. We always called them WAGs, or Wild Ass Guesses. "I don't know," is never an answer that your superiors want to hear, so you give them the best guess with what you've got. Sometimes you don't have shit, but they still want answers.
So intelligence is a field in which all you're doing is guessing and hoping to Christ that you're right. Your successes will never be known to the people you care about, and your failures will be plastered in plain sight for all to see. People mock you for failing so much, but don't realize that successes are kept under wraps because if everyone knows what works, it doesn't work anymore.
So if you're into dealing with guess work, never getting to talk about the cool shit you've done, and enjoy getting shit on by a public who doesn't even understand the nature of your work, then work in the intelligence field. You'll have a ball.
