Unless you are good enough to write, draw, ink, color, and letter your own book (and there are very few who can do it all), you’re going to have to work with others.
There’s a right way and a wrong way to do this. The right way comes from a place of mutual respect. The wrong way treats the creative team like underlings, and unless you’re paying great rates, they won’t stand for it for very long.
Respect is like a two-way street, but the trick to getting it is simple: you have to give it, first.
Walking through the mall, do you smile at little children? Do you open doors and wait for people who are right behind you? At restaurants, do you thank the people serving you or clearing your table? If you work in an office with a cleaning crew, do you thank them for the job they do?
All of those are ways you can give respect. People are not beneath your notice. So why would you treat people who are helping you to create something that is bigger than yourself any differently? Sometimes, they’re treated worse. Why?
There is no such thing as an easy job in comics. Writing isn’t easy, because you have to know a lot about how to create a story that works for the medium. Art isn’t easy, and is extremely time consuming. Coloring isn’t easy, because you have to decide the palette and light sources and special effects and more. Lettering isn’t easy because you have a lot of rules to follow in order to make the reading experience seamless. Editing isn’t easy, because not only do you have to know something about all the other jobs, you also have to deal with personnel and their personalities, and get them all on the same page (heh) to create the book within a reasonable timeframe.
Working with others can be a challenge, but it’s a challenge you need to be able to negotiate. Quite literally, you’re going to need these other creators in order to make your comic. Respect them and their needs, and they in turn will respect you.
Remember, you have to give it to get it.
