Weiran Liu wrote this book when she was in fourth grade, and when she had an interest in Science and Writing. She liked writing and wanted to share her passion with others, so she started writing. A passion in yourself is true, and she wanted to share hers. A passion can help start your true self and inspire you to do amazing things that can even change the world. If you don’t have a passion, you might give up even before you finish a project. That’s why it’s important to know the project you’re doing before you’re going to do it.
