Yeah I feel like I hide in those tasks to achieve a sense of accomplishment while also avoiding the uncomfortable task I should be working on. Then again, those tasks help me pass the time until the deadline for the important task is close enough to generate the fear/anxiety necessary for me to work on it.
And it's so satisfying to something that gives you physical feedback (doing dishes, vacuuming). Most of my day is spend doing math or programming so all my works takes place on a computer, a piece of paper, or in my head.
