It is thought that perseverance is equally as important as talents when it comes to writing. You need to develop as a thick-skinned as bulletproof and recognize that not everyone will like your style of writing or be interested in the topics you choose to write about. This is especially important to recognize earlier on, before you start to write Books.
A good way to gain experience prior your settle down and write your very first book, is to submit your works to print publications to see if you can actually sell your writing. If you want to write Books, you may try getting used to the process of querying and submitting shorter works to Editors, which in return will help you gain experience with the whole process of publishing your own written works, and especially to help you find out how you would deal with rejection.
Many Writers begins with a grand goal in mind, and that is to write Books. However, when you are embarking on a career in writing, it is better to gain experience with other forms of writing such as articles and short stories before submerging yourself in such a grand and time-consuming project.
You will probably have some victories along the way, especially if your writing is quite that good, but for the most part, Writers may experience much more rejection than acceptance for their work.
If you fall apart the first time you receive a rejection letter for a short article, it may sound better to acquire a different career. Imagine how you will feel when you spend even more of your time and write Books that are then rejected by more publishers. You need to be able to pick yourself up, dust yourself off, and try again repeatedly, until you finally get your "Yes."
When you write Books, you will have to become comfortable working with an Editor to get your story or ideas into a format that will sell. You are the Author and the ideas for the book may be yours, but the Editor knows the audience more and can help you to shape your work to reach your audience successfully.
If the idea of others having input into your work bothers you, you may want to write Books and publish yourself. Because of the Internet, there are many more markets available to Writers, such as Self-publishing and e-Books. You are not likely to make a lot of money writing Books for digital distribution but it will allow your creative freedom while also helping you hone your skills for those years to come.
