I develop apps and after I have completed 80% of the crucial work, the remaining 20% of the work involves boring and brainless stuff like adding in app purchases, adding features like send feedback to developer, asking for reviewing the app, designing the app icon, designing the App Store screenshot, writing the metadata for App Store description etc.

I procrastinate super long on this 20% of boring task even though it could all be done in maybe 2 days.
