Let's Talk Projects/Classes that Overstay their Welcome

My first page - describing the purpose of my sketchbook and featuring one of my recent face paintings.

Last spring, I signed up for the Sketchbook Project (see this post for details).  My theme was "In  ten minutes," and I set it up as a smashbook, with prepared backgrounds that I could easily add to and thus create an interesting page in ten minutes or less. When I signed up for it, I thought it would be an easy project to complete. Plus, the deadline was not until the end of January. I started off with a lot of enthusiasm, but it soon languished on my desk with only the occasional entry. Now, with the deadline just a week away, I found the sketchbook and decided to finish it up.  Some pages feature my thoughts about the day's events:

The page on the left chronicles some of the things I accomplished in getting healthy; the page on the right reflects on Sept. 11 - ten years later.

The page on the left is about our vacation to Seattle and the San Juan Islands. The page on the right talks about the upcoming soccer season for my son's team.
Others deal with how I'm feeling about things in my life.

A page about some of the struggles in raising the kids.
A few are just happy art.

As you can tell from the title of today's post, I think this was a project that overstayed its welcome. I should probably have realized that before I signed up for it. I'm best with short-term projects.  I like online classes that are 3-4 weeks long; any longer, and I start to fade. I did fine at the "week in a life" and "photo-a-day for a month" photography projects, but I know I could never do Project 365.  On the other hand, as I finished up my pages today, I found that I really enjoyed them. And, in looking at my completed pages, I was happy that so many incorporated actual drawing and sketching.  These pages feel very different than my art journal pages, and they track the advice about making a sketchbook in the book, Painted Pages, which I'm slowly working through. So, although this does feel like a project that overstayed  its welcome, I feel like I still got something out of it. And, in the end, I'm glad I did it. It also feels good to have it completed. I'll mail it off tomorrow.
So, let's talk about it. . . have you ever started a class or project that overstayed its welcome? Did you regret it? Or was there a benefit to it? Do you feel compelled to finish or do you just let it drift?  I'll leave this post up for a couple days, as I'd love to hear your thoughts and opinions!
