“Sometimes comparing can be a good thing: it can inspire us to work harder and reach farther. But for the most part, excessive measuring yourself up against others - especially when it becomes a way to put yourself down - is a colossal waste of time. It's a dead end. It won't make you do anything except feel horrible.”
