In a person's life, only you know whether you are doing well or not, and only you know whether you are happy or not; life is short, there is no need to regret whether it is good or not, and don't be disappointed whether you are happy or not. A good life is wonderful, and a bad life is an experience; life is short, as long as you have done your best and used your feelings, there is no need to regret in your heart, let alone remorse.
