How I want to live mercilessly.

Let yourself be selfish to the extreme and don't care about any opinions of others. . . However, if you can't stand being told that you are selfish, let yourself be indifferent and don't care about anything, including your own affairs (I think it's better not to be selfish, such people are so hateful that they harm others and yourself). You should be happy, sad and angry, but as soon as things are over, you should forget what just happened and immerse yourself in the local atmosphere at that time. The atmosphere has changed, but don't let your mood stay stagnant. . . . . To tell the truth, you just have to force yourself at first, and you will get used to it after a long time. . . However, I still wish I had a little heart and lungs. If I want to be ruthless, I want to stop my own pain, but a completely ruthless person will make others suffer. Such people are disgusting.
