Hello everyone. To improve one's writing, one must learn new things. It's as easy as joining a writing group to as time consuming as going back to school.
If your friends say you tell wonderful stories of your adventures or everyday life then you should write them down. They may not be in perfect form, but you have started. Maybe you have always told stories but only in your head, write them down. It can be as detailed as you want. Maybe you wake up in the middle of the night from either a wonderful dream or a nightmare. Keep paper and pencil by your bed and write the dream down. This is how you start to become a writer.
But, how do you improve your writing? Maybe you were a natural in English class in high school and always did a great job. But, if you are like most of us, you did okay, and could really use some improvement in the writing department.
The first thing you should do is join a writing league or writing group. It all depends on the area you live in for what is available to you. I am a member of the League of Utah Writers, the Oquirrh Chapter. They have a meeting once a month. Each meeting is different and provides valuable information. Most meetings will have a speaker who will come in and talk about the craft of writing. S/he will talk about grammar, syntax (the arrangement of words and phrases to create well-formed sentences in a language), character study and development and anything else related to writing. Always take a note pad and something to write with. Some people like pens other people prefer pencils. Just don't forget to bring them with you.
The second thing you should do is to take a class. Although the presenters at our league meetings are usually published authors, they are not teachers. They are just passing along what they have learned. Take a class. Your local community college may offer a night class for several weeks. It could be specific or generic. Specific it could be a class to learn how to write poetry, film/TV scripts or novels. Generic, it could be just how to improve your writing.
Your other option for taking a class is to actually go back to school. And that is my plan. My plan is to return to school and earn a BA in English with a Concentration in Creative Writing and a Minor in Publishing Studies. Now, going back to school may not be ideal for you. But you can still take a class here and there to help improve your writing.
As your writing improves so will your chances of publication. Always take the opportunity to learn something new. If you're already a published author, take the opportunity to give some of your writing wisdom/knowledge to those who are wanting to learn the craft. It will be greatly appreciated.
