I agree with what others are saying, it's a worthwhile skill to be able to work with others if you're ever looking to do art besides just promoting/selling your own. It's not a bad skill to develop.
And it can be fun to work with others. I have a friend that, when we are together, we seem to spark each other's imaginations and come up with stuff that we might not otherwise. So ,for a while now, we've been working on a collab. It's pretty light hearted and fun, and (I think at least) interesting learning how to bring our ideas together.
However, I also have stories of my own that I want to tell, and I want to be in charge of all of it. So, aside from asking for advice or opinions, I handle all the work for those stories.
