I'm going to identify at least twelve books this year that I've been meaning to read but that I've put off for lack of confidence that I'll have time/energy/skills. These don't have to be "challenging" for any specific reason: the point of the challenge is to take on books you personally need an extra boost of confidence/motivation to tackle! Bonus prompts should give you some ideas of what "challenging" can mean, but it really can mean anything!
