Spend time with writerfriends, especially if you work from home and don’t have “coworkers.” You do have coworkers—they’re the people in your field who you know and trust and tweet with and email with and would like to know. Internet writerfriends are still writerfriends, and they’re great candidates to becomes real life friends.
If you’re socially awkward and/or anxious like me and every other writer, do your best to push through that when you can. You’ll pretty much always be glad you did. There’s a high premium on HUMAN CONNECTION, and you don’t really get it on the internest very often.
also: cultivate writerfriendships that allow you two (or more) to get together and not just “hang out” but to also both be working on your computers or phones or notebooks. it’s not only fine, it’s fun, and challenging, and awesome.
