Once you get into the industry you might come in with a naive notion that you're gonna make the game/film you want to make. Better build a bridge and get over that ASAP. More than likely you were hired to do a specific job (unless of course you own the company which is another conversation). Keep your life dimple. Do the job you were hired to do. Other opportunities will arise.
Working with other people as a team can sometimes be challenging, especially if there are personality conflicts. With luck, the company that hired you has similar people like yourself. Do all you can to remember that the studio's work is about the project and that everyone has a common goal. There will be times where you will have to work with someone that you'd rather not work with. Make the best of the situation. I
guarantee you'll learn something. I've had to work with people I was not a fan of in the same office. I was able to find something in them that I could respect. I mean, there's a reason they got hired. They were good at their job, and I learned a lot from them.
The shipping of a product should never be reliant on just one person. It takes a team to complete a product (there are exceptions of course, like some indie studios). Nor should the product be beholden to whether or not the teammates get along with one another. If it's so bad at the work place then it may be time to find somewhere else. And that's OK. A workplace, in our industry, should be conducive to creativity and solving problems, not feeding one person's ego.
Working for yourself is another matter. It can be very fulfilling, so long as you treat it like a job. Example: You have to ship your product at some time, therefore it just has to be good enough. You have to have limits and maintain goals, otherwise you can go on forever on whatever you're making. Even after you ship you still have to rely on others to be successful. Like those who purchase what you make.
Everyone on the team takes their victories and lumps together.
