How do I stop comparing myself to others and run my own race?

You have reached a rare and steady place. You can watch someone else win and feel glad, not diminished, because you have stopped mistaking their highlights for your scorecard. That freedom is worth more than most of the things people are competing over. The reason it works is that you have your own measure. You judge yourself against your values, not against the polished pieces of other lives that show up in your feed. Their success is theirs. It takes nothing from you. Your race has its own finish line, drawn by what matters to you. Keep the measure clear and close. Every so often, write down the few values you actually want to live by, and check yourself against those. When comparison creeps back, as it will, that list brings you home. You are running your own race well. Trust the pace you have chosen.
