Step #1 Learn to work with others

Working with your friends is great. However, your odds of success increase when you select your team based on their talents. I'm not talking about diversity just for the sake of diversity. I'm saying that your friends may lose interest in the project, show up late, or not at all.
Project Managers
Select someone that shares your passion for the project. They may not be someone you want to hang around with; they may be older or younger but as long as they are civil, honest and show up to work and follow the project plan they may be the best choice for your project. You need to get experience as a team leader working with different personalities. If you can only work with your friends, you're not a very good leader.
Last, you need to learn about running a business. You may not want to call it a business--but don't make things more difficult by lying to yourself. It is what it is, keep the fantasy in the game.
Team Members
If you're the person being hired, you need to understand that everyone working on the project is of equal importance. The odds are you probably won't get rich, but if you don't finish the project, you won't make any money at all.
Some artists and writers tend to have antisocial or reclusive personalities. Those personality types can be "overcome" unless there is a great deal of ego or paranoia involved. Some people think that every opportunity is an opportunity to be ripped off. Or perhaps they feel that their talents are so great that they should never be asked to take an equal share of the risk.
A good example, if you look at all the failed games and comic books over the last 27 years, the vast majority of them had really good artwork & writing. So, if you're working at a Star Bucks, and not as a professional writer, artist etc., then you shouldn't ask or expect special treatment from the other team members. In fact, most amateur teams consist of an amateur artist, an amateur writer/designer and a professional programmer. Yet, the programmer almost never gets paid up front or gets a larger share of the pie. Bottom line: restrain your ego until you actually complete a project.
