As much as I enjoy reading about the many and varied book challenges around the blogsphere, I tend to avoid joining them. My reason for this is simple - if I put too much pressure on myself about my reading it stops being fun and I get all stressed about it. Since I tend to find my TBR stress enough, I try not to make it worse.
So I only joined two challenges in 2008 and had a 50% success rate.
Here the challenge was to finish three books that were already on-going unfinished reads. Sadly, of the three I only managed to complete one and as the end date is the 15th November (ie 4 days away) I know I won't be getting either of the other two finished in time. I still hope to complete them at some point, but I didn't make it in the time frame of the challenge. [list]
I'm already tempted by some of the 2009 challenges appearing, but so far plan to go with just two that I'm pretty confident I can manage to complete. We'll see if anything else wins me over.
