A marker of wisdom is the ability to deal with reality without negative emotion when it isn’t favorable.
It often means saying things like…
That game didn’t play out the way I hoped.
I made a costly mistake that my team will unfortunately have to pay for.
That person hates me for reasons that aren’t particularly fair.
There’s no repairing that error.
… without necessarily letting ourselves become overcome with frustration or anger.
Those emotions rarely help.
There’s no point screaming at the large pothole on the road outside our home everyday.
Either fix it or find a way around it.
In either case, the emotion isn’t necessary… or helpful.
