"No man is an island," and all that jazz.
Things are going pretty well for me, and the London attacks served as another reminder of just how lucky I've been for a long time running now.
When the biggest complaint I have is "I spent Monday and Tuesday refactoring code that should've been done last week"... well, it doesn't amount to much, really.
Someone once said 90% of life is what happens to you and 10% is how you react to it. I've been a lot happier ever since I started concerning myself solely with that 10% (heck, just that little bit is quite enough). But that doesn't mean that you can ever completely isolate yourself from that other 90%.
Nor should you. And so, I'm allowed to be depressed by the London attacks. I'm not a kid: I've learned by now that humanity is capable of soaring to incredible heights AND sinking to unimaginable lows.
But if I stop being surprised by those lows, I'll feel that I've lost something.
