What inspires you?

Recently, I have begun following Gretchen Rubin's Happiness project. I came upon it quite by accident, and now I look forward to her little piece of insight in my inbox every day. Now those of you who know me know I am generally a happy person, but I've never really given it much thought. Well, Miss Gretchen spent a year thinking about it which she made her blog and book. She's got some really interesting insights, that I had never thought about before like 10 ways money can buy happiness. I urge you guys to check it out!
