Not really. You just have to get a strict schedule going and stick to it. The way most artists do it is to have 6 months to a year's worth of books or strips (depending on what format you want) complete before publishing and distributing the first one. That way they have a big cushion of time to continue working and stay caught up. The average speed of a good comic artist is one to two pages a day in final pencils. Inking is probably about two maybe three a day and coloring by hand is probably one. Sometimes you can hit a good stride and belt out more, but just as much you will encounter a block and dawdle on one page for a day or two.
Another trade secret a lot of the big guys have (like Stan the Man) are ghost artists. They hire other people to draw all the back grounds or all of the buildings and then they go in and just draw the main characters and go over it to make it look co-hesive. It's the same with some book authors. The person who's name is on the book just makes a detailed outline and lets a group of underlings write the story in between. At the end they read it and edit it to make sure it fits their personal flavor and then send it out. That's how they get out so many books a year.
I actually got to work as a ghost artist on a comic by a very big name in comics, I drew all of the trucks, some one else drew all of the trees and backgrounds and some else drew all of the buildings. The man that got to put his name on the book came in at the end and drew all of the people and made sure everything was up to par and shipped it off to the printers. I got paid well and it was a ton of fun. Plus I got to work alongside one of my inpirations for going into comc book art.
