The best purchase I ever made without regrets is my books and Scrivener. 

As for books, for me, they carry immense value and knowledge. They are the most precious possession someone can attain. 

Let’s go to Scrivener. Scrivener is a fantastic program for writers, offering many features to make your writing journey more convenient, from gathering information in files and creating cards for your characters at the beginning to your main text and its outline. In the bottom line, Scrivener is one of the best programs for organizing your book in progress.
