How do I stop wondering about the opportunity I turned down?

You turned down the move, and the reasons felt solid at the time — comfort, fear, a life you did not want to uproot. Now you carry a quiet question about the person you might have become somewhere else. That wondering is honest, and it deserves to be met plainly rather than pushed away. Here is the thing about the road you did not take: it stays forever perfect because it was never lived. The you who moved would have had hard days, lonely stretches, and regrets of their own — you just never had to meet them. You are comparing a real life, with all its texture, to an imagined one that never had to disappoint you. That is not a fair fight. The choice you made was made by someone with the information and the fears they had then. Judging that person now, with today's eyes, is a kind of cruelty. Instead, ask what that imagined life was really promising you — adventure, growth, a bigger version of yourself — and find a way to give yourself some of that here, now. The city was never the only place to become that person.
