I'm currently rereading Eat, Pray, Love because I loved the message so much. It reminded me how important it is to nurture yourself and to never let anything stop you from doing what you want. It inspired me to take more time for myself and to not feel bad about putting my needs first. It also motivated me to write in my journal more, learn how to play guitar (a long-time goal), and spend more time with my friends and family.
There must be a book out there you've read that's touched or inspired you in some way, so tell us about it in the comments below.
