Winner take all
Almost nothing in our daily lives is actually a winner take all competition.
Somewhere, there's someone fitter, faster, thinner, quicker, smarter, more popular or richer than you. And there's someone else fitter, faster, thinner, quicker, smarter, more popular or richer than they are. And you're (far) ahead of someone else who is busy looking at you from behind.
And yet we see people angry because someone's passing their car, or gaining more followers online. They mistakenly believe it's a race. It rarely is.
If you can use your situation as fuel, fuel to dig in and care more and do better, by all means.
But if not, ignore it. Do your work, not theirs.
