Ui is just for a meal, he has no talent."
In your daily life, because success is more visible than failure, you automatically overestimate your chances of success. Being an outsider, you can not resist an illusion and you misunderstand the probability of success in reality is how small.
Behind every famous author, you can find 100 other writers whose books will never be sold. Behind them are 100 other people who have not yet found publishers. Behind them were 100 other people with unfinished manuscripts sticking dust in the drawers. And behind every one of them is 100 people dreaming about writing a book someday. However, you only hear about successful authors and do not realize how successful literature is. The same is true for photographers, entrepreneurs, painters, athletes, architects, Nobel laureates.
