To challenge or not to challenge

I thought it would be nice to visit the blogs of those who have signed up for the TBR Challenge. I was going to write down books from their list that I thought were interesting. I'm thinking it was a mistake. One of the bloggers has a whole list challenges she belongs to. Overlap is possible between challenges but still... 22 challenges? Someone needs to slap me because I'm considering adding reading challenges to my already overwhelmed outside life.
