There was once a man who went on a journey to correct his regrets. He tried his best to change the past. Unfortunately, the door to miracles never opened for him. He realized at the end of his journey, no matter how hard he tries to change his past, he cannot change himself. That is why he tought, instead of regretting about the past, what’s most important is to change the present for the future.
