In 1949, Edward Murphy conducted a rocket sled experiment to see how much pressure a human being could withstand.
Murphy's experiment failed spectacularly, over and over.
Needless to say, he didn't start off on the right foot.
That's why it's called Murphy's law.
Because if anything can go wrong, it will.
Once things start going wrong, it's hard to break the cycle. Murphy's law is not physics. It's just a thing a guy said to try and make sense of a crappy day.
Just because things go wrong, it doesn't mean they're out of our control. It's on us to fix things. It's on us to take everything that can go wrong, and make it go right.
It's on us to try, anyway.
