How far out into the world? Tolkien wrote The Hobbit for his kids, after dabbling in writing stories for the preceding 10 years or maybe longer, and he showed them to his friends sometimes, and a friend showed it to her friend who showed it to her boss, who published books, and this chain of events led to Tolkien having to write The Lord of the Rings. He wasn't exactly shielding his work from criticism, by writing for friends and family, but he wasn't throwing himself to the lions either, because why?

By "human value", do you actually mean "monetary value"?

Many of the most famous artists were unknown or unappreciated in their time, and if they'd asked the people around them whether their art had value we'd likely not have half of the Louvre.
