The time keep flying as we keep walking on the path we chose. sometime life is goes faster than the blink of the eyes and when you notice yourself again while you keep chasing your dream on the long run. you still standing behind the started line. So no matter how fast you can run, time always up ahead you and you cant catch it. no matter how hard you will try. just understand the nature. like the song in this piece. you'll get a sadness feeling at the last chord of the song.
