There are many ways to becoming a better writer. Like many things, not one set path gets you there. Determine what you want your goals to be, and then set out to accomplish them, not goals that someone else gives you. If an English professor is training you to become a reporter and you want to be a novelist, drop the class. Become the writer that you want to be.
Just like riding a bicycle, cooking, doing autopsies, or painting, writing takes practice. So practice! Look for any opportunity to write, and do it. Are you in school? You get to write papers? Does your school have a newspaper? Go into their offices and say “I want to write for you.” Look online. With the Internet revolution, websites after website has to have content on each page, and they need someone to write all of that. There are plenty of organizations that hire content writers and provide them with work online, or you can approach companies alone and offer your services. Writing never goes out of style.
Writing is how we communicate, and the human race will never need to communicate less, quite the opposite in fact, it needs to improve. And as a writer, you get to help the rest of us improve!
Practice, practice, practice. Take advice from others, but remember that you get to set the rules for your writing education and how you go about doing what you do. So go and do it!
