Everyone comes into this world with their own life path. But the track is not built by others for you, but built brick by brick by yourself. Those bricks and tiles are the choices you make in life one after another, the little things one after another. When people live in this world, they are always making choices and building their own trajectory. Your trajectory is not truly completed until the day you leave this world. The day when the track construction is completed is still a long time away for the girl, so she has been making constant choices and working hard to build her own track.
