There will always be something wrong, if we keep looking for it.
We don't live in a perfect world. We don't live perfect lives. And we don't have to strive for perfection.
So if we always look for mistakes, for something to complain about, for something to criticize, we will find them. We'll find many.
And if it's something we do everyday, it becomes a bad habit. It affects our mood. It affects our perspective of the world. It affects what occupies our minds. It affects who we are.
Don't look for mistakes to judge. Look for things to celebrate instead. We should surround ourselves with inspiration and possibility. That will affect us too, our lives and our characters—bringing with it compounding rewards.
