#跟单交易 Once I was kinder than anyone, more sincere than anyone, and softer-hearted than anyone. It is reality that made me see through human nature, it is lessons that made me understand people's hearts, and it is time that made me realize that being soft-hearted only allows others to take advantage of you. Kindness can become a sharp blade that others use against you. I am still me, but I am no longer the person I once was.
