Whenever I get too worked up about how decisions are made in my group, I like to think of all the IT departments there are in my city, in the world even.

I don't care about what decisions are being made in those places, so I shouldn't get too worked up about decisions being made where I work either.

If, after giving my recommendations, and making my arguments, people still decide to do risky dumb things with infrastructure, I don't let it bother me anymore.
