如果你看到面前的阴影，别怕：那是因为你的背后有阳光！
If you see a shadow in front of you, don't be afraid: it's because there's sunshine behind you!
你只管努力，剩下的交给时间.
You just work on it. Time will do the rest.
记得向前看，别烂在过去和梦里.
Remember to look forward, don't rot in the past and dreams.
间歇性的努力和蒙混过日子，都是对之前努力的清零.
Your intermittent efforts and muddling through are a clean sweep of previous efforts.
