A good chunk of the money I spent on Writer Pro is to pay iA to obsess for me. Go watch the videos. They’ve clearly spent hundreds (thousands?) of hours considering the many aspects of writing and attempting to make the best decisions for me: the writer.
The entire article contains good design advices, and the above excerpt is not even the main point. I just like the idea of delegating obsessions to those with the same mindset. Because while obsessing about something can yield good results and at the same time fulfills some emotional needs, it can be a major drain of time and energy.
