When i talked with my new friends in taiwan i was impressed with one's answer.
I was talking about a bad experience and depressed.
The answer was "You have to experience a bad thing to discern what is good."
It has been being helpful to me.
I hope this sentence helps you too.

翻译：当我和在台湾的新朋友们聊天时，有一个人的回应让我印象深刻。
我那时候在讲糟糕的经验和令人沮丧的事情。
那个回应是：“你必须经历过糟糕的经验才能辨别什么是好的。”
这让我受益良多。
希望这句话也能帮助你。
