Some people have asked me how often should they write. In the beginning stages of your career, you need to write as often as you can. Does that mean every day? Sure, if you can. If not, don't worry about it. Whenever you put down words, make sure they are the best they can be. Make sure they're commercial.
The next question is always "how do I know what's commercial?" Read what prominent authors write. Read the best sellers. Then, by no means, copy other writers. Find your voice. But, incorporate what works for you into your work. If the story is good, people will like it.
