When we were young and ignorant, we always cared about it, cried and begged for comfort when we suffered the slightest grievance, hoping to get some childish compensation. As everyone knows, an injury is an injury, and no matter how much compensation we make, we can't erase the traces of heartache.
After being polished by time and seeing the impermanence of the world, I wish I had a time machine.
Go back in time and tell yourself: let go of those childish obsessions and cherish everything you have.
