You can live a big life in a small town and a small life in a big city.

The size of your surroundings and the size of your life are separate measurements. Big is made of what you do and who you know: whether you are useful, whether anyone would notice if you left, whether you are still learning anything. All of that fits on one street, and none of it is guaranteed by a city of millions.

Define a big life for yourself in one sentence that does not mention a location. Then check whether your current plan is about the place or about the content.
