I also worked solo -- at home for one year and in a private office at a coworking space alone, and then with an officemate, and now finally working at a company in an office. Each incremental step has been better than the next and I do not want to go back. Working solo at home was especially horrible (and I'm an introvert). I would like to have flexibility, i.e. Fridays at home (or off totally) would be ideal.
