The goal is always to try to merge the two. Drawing comics is an incredibly creative way to express an idea through story and art.

Look at art styles and stories. After a few we'll start to see a slight pattern, a rhythm. Learn to work in that scope or pattern to shape out your comic.
Its not always what you want it to be so be prepared to step out of your comfort zone. Know your readers. Have avenues to communicate with them and listen to feed back. People are talking to you because they want to continue reading your story and be part of the adventure.When you draw for money you draw to please your buyer. Look for art that sells or is really popular. Learn why people like it from their point of view and learn how your art can take on that type of value. It could be that you need to update your art style or choose a better gimmick for your stories. What ever the case is you need to start looking into it.
Remember that personal art is for your own pleasure and commercialized art is art that needs to sell.
