“Be ruthless about protecting writing days, i.e., do not cave in to endless requests to have 'essential' and 'long overdue' meetings on those days. The funny thing is that, although writing has been my actual job for several years now, I still seem to have to fight for time in which to do it. Some people do not seem to grasp that I still have to sit down in peace and write the books, apparently believing that they pop up like mushrooms without my connivance. I must therefore guard the time allotted to writing as a Hungarian Horntail guards its firstborn egg.” - J.K. Rowling
This applies, I think, not only to writing, but to all creative work, and to working from home in general.
Images: The illustrations at the top of this post are "Working from Home" and "Dragon Pest" by the London-based illustrator & animator Carmen Bromfield-Mason, whose work I love. (The first drawing is a self portrait, with the artist's cats Kimberly and Titan.) The little sketch at the bottom is by me.
