I recently got a tenured (yes, permanent) faculty position in mathematics. During my PhD and postdoc, I collaborated with the same people on some projects, one big and one small, but most of my time was spent on my own, single-authored projects.
This clearly worked, however I now feel like I am missing out. I see all these people at conferences interacting, breaking ground on new knowledge together and having rewarding time working with other people. How do I get to that point?
Not to fall into stereotypes, but I am unfortunately a bit socially awkward, which does not help. I can go out and have fun with other young mathematicians, but walking up to someone and starting talking about a topic of collaboration seems to be out my reach. It never goes further than "I have a question", listening to the answer, and going back to talk with my friend-colleagues.
