You may be told you’re too young to write, the argument being you haven’t lived enough so how can you possibly capture the essence of life and pour it into a book that’s meaningful and engaging?
I started at a very young, and when I read what I’ve written back then, most of it is complete garbage. It’s infantile, naive, too quickly paced, too easy, too… too young! But I would never discourage anyone from starting at a young age, nor do I regret starting at a young age. While you may not find anything you’ve written in previous years useful (and conclude it was a waste of time), you still wrote. You thought about plot and characters. You took the time to think about why you want to write and what kind of story you want to write. You let your imagination run free. Maybe you even thought about your competition and read books in your genre to understand what makes a great novel. You’re never too young to start pursuing something you’re interested in, whether it’s writing, acting, directing film, sports or something else.
Even if what you’ve written in your early years turns out to be useless, it is still good practice and you force yourself to establish a routine. It takes a lot of dedication and time to pursue something, and there is no perfect age to start at.
Another important aspect that I realize now, is that when you’re young you have a lot more time available. Even with school, homework and extra-curricular activities, you have a lot of time to explore a creative path. Furthermore, the fact that you live with family means you don’t have expenses to pay for. You don’t have to get a job to pay your rent and food, so you’re freed from obligations you have as an adult.
Writing a book can teach you a lot of valuable skills. It requires not only creativity, but also focus, perseverance, establishing and adhering to a routine, excellent level of grammar & language skills, communication skills, thinking outside the box, research, attention to details, sense or commercialization and entrepreneurship, and many other skills… All qualities that can be useful in many aspects of life. So I would always encourage anyone to write, regardless of age.
