Totally love the song 不敢哭 by Lara.
Watched the mv that just recently got released for it, and some word inside the movie really makes so much sense.
As much as this is a sad love song, the context just basically about applies anywhere.
得不到的就该放手 就算哭了 还是勇敢的
Which translated means, if you can't get the thing(person), you should let go. And even if you cry, you are still brave.
Honestly, be it love or not, this really should be adhered to!
Just some food for thought anyway:)
