"I think if you were trying to pair up writers, you probably would say it’d be good to have someone who is more intuitive and goes by feeling and does just what feels right in the moment, and then someone who is really good with story, and nuts and bolts and conceptual look. Both of us are much more in terms of feel. We don’t have the nuts and bolts guy in the organization."
The difficulty is that we tend to like working with people like ourselves and the more alike two collaborators are, the less they actually need each other. That often leads to each person to thinking they're providing all the value and the other person is getting all the credit.
Where can you find potential collaborators? In writing classes, writing groups, and even online.
But before you commit to any long term collaboration, have a bit of a trial marriage first. And when you do start working together, put everything in writing. Like many marriages, it always starts with sweetness and light but, sadly, sometimes ends in acrimony and different ideas about what was agreed and who did what.
