> I have special place in my office where I put a book so that it is visible to me whatever I do. It serves as a constant reminder to get it finished.

Tangential but I do this with everything. I like very high levels of organization (blame my aspergers) and thus I found that my motivation to hide unnecessary things from view is pretty high. High enough that I place things in view as a reminder to get them done. An extra laptop on my desk -> I need to transfer the remaining files into my new laptop so that I can finally remove it from view. Book on my desk? Needs to be finished. Sticky note on my island? need to order groceries before I can remove it. I'd turned minimalism into a lifestyle/todo list. Same with the digital world.
