I guess that's a problem for a lot of us who learned to program as teenagers. A big reason programming felt good for me is precisely because it let me do interesting and impressive stuff myself, and not collaboratively. There were very few kids who had even remotely similar interests to me back then - and that's true in adulthood too, outside of work contexts. While on the job, my projects may be collaborative in nature, but after hours, there's very few people among my family and friends who'd even be interested in doing a small software project, much less capable of doing so.
