If you're spending at least part of the summer writing, and if you're interested in maintaining your motivation and productivity, then ProfHacker's Writers' Bootcamp Summer Writing Edition shares several tips and suggestions by which you can't go wrong.
One of the suggestions is to make writing social, and both online and face-to-face writing circles are mentioned as arenas where "you can encourage and challenge each other. You can hold each other accountable. [And] you can celebrate your writing achievements"
Remember that the Center for Faculty Development sponsors a writing circle that accomplishes all of these objectives through a hybrid [part online, part face-to-face] approach. Limited space is still available this summer in the writing circle, so if you seek not to be lonely in your writing, email an expression of interest to Mark Potter.
