Disgruntled Security Guy?

I'm a security guy. My first thoughts when I hear a new product announcement aren't how great it can be. I think of how it can be broken; what protections or features the maker might have forgotten to include. Yeah. I'm that guy. And actually, there's quite a few of us out there.  We oftentimes rant and rave through various channels, including online and print media, blogging, and even bitchfests about the world shared with friends and family. The security profession breeds a worst-case-scenario, quasi-pessimistic mindset that I'd like to open for discussion. 

Is it bad to have this mindset?

• On one hand, you could say that the worst-case-scenario mindset is a negative outlook that ultimately leads to an unhappy life. The security guy's mind (and/or mouth) is always going 10 picoparsecs per hour about what's wrong with the world and how stuff would be better in his orderly utopian world. The one with civil liberties and stuff.
• On the other hand, some people just have a knack for breaking things, and processes. Some of these folks become NASCAR drivers. Others become lawyers. And some become security guys. We like breaking things. To us, it's not necessarily negativity. We just see a different problem than everybody else. We don't want to solve Rubik's cube. We want to figure out how to take it apart. We divide by zero when faced with people who can own a device and just use it without understanding every mode, menu, and function.
• Furthermore, I'll posit that it takes people with this mindset to keep stuff evolving. Without the perennially dis-satisfied, who will drive things to improve rather than shrivel from complacency? I believe this dis-satisfaction is the core of the human spirit, and it's what drives capitalism and makes this country great. Maybe it's just a red pill vs blue pill question. 

So... am I a disgruntled security guy? Nah. I'm actually quite gruntled. I just love breaking stuff. :-) Am I a disgruntled civil liberties guy? Yes. That just has to do with being annoyed by morons who look at (or even design) a bug and then call it a feature. But I recognize that it could be a lot worse and I am thankful for the civil liberties we still have today. Share your comments! Cheers, Andi Oh... I'm writing this on an airplane. For the safety of everybody onboard, I've just been instructed to shut down all my electronics in preparation for the landing coming up in half an hour. I'm surprised they haven't banned electronics since they're so dangerous. I'm sure it's in the pipeline.
