Those who turn back never reach the summit.
回头的人永远也到不了顶峰。
I always turned back on my life road, so it's destined that I will never reach the summit, even may fall behind to the one I used to be.
You can't get so hung up on where you'd rather be, that you forget to make the most of where you are.
不要太执着于你想要的，而忘了你可以用好你所拥有的。
Make the best use of what you have now, that's the basis of the future you are eager for.
