I'm reading The Happiness Project by Gretchen Rubin, and one thing that she defines in the book and mentions a couple of times is the concept of boomerang errands. In her words:

I faced a discouraging number of "boomerang errands": errands that I thought I was getting rid of but then came right back to me.

Eighteen months overdue, congratulating myself on crossing the task off the list, I went to the dentist to get my teeth cleaned, only to discover that I had decay under one filling. I had to return to the dentist the next week. Boomerang.

After months of procrastination, I asked the building super to fix our bedroom wall light, but it turned out he couldn't do it. He gave me the number of an electrician. I called the electrician; he came, he took the light off the wall, but he couldn't fix it. He told me about a repair shop. I took the light to the repair shop. A week later, I picked it up. Then the electrician had to come back to install it. Then the light worked again. Boomerang, boomerang, boomerang.

I think this is a really helpful concept!
