This is my first attempt at writing a novel and publishing it. This will also give me the motivation to stick with it. I hope I can do it. I plan to write down the things I regretted not doing in the past time into the novel, and create an image of what I should have been like as a teenager. Maybe I think this image is almost perfect, but maybe it seems very naive to others. I just want to use this image to tell myself, just do whatever you want to do. A hundred years of life is not a long time. You can regret what you have done, but you must not regret what you have not done. If you regret something you have done, you can forget it, and you can still be a good man if you delete the memory, but if you regret something you have not done, you cannot regret it. Being immersed in memories is always escaping, and the best way should be to follow the road ahead. I want to become comrades-in-arms with the protagonist of the novel, and walk a path together that will make me regret less (I also know that there is no regret without regret), so that my current self can have the confidence to say to my future self: "Don't worry about recalling the good times in the past, I will never make you regret it."
