The author, Gretchen Ruben, says this is an approach to changing your life. She did a different thing every month and documented what she was trying, what she learned & even started Happiness Project Toolbox website!
She writes like she is talking directly to me (or you, in your case ) while putting me into thinking mode. She is very clever.
Trying new things in my life is an on going thing so why not meet new people, have new stories and experiences to share. All while creating your own project.
Be more polite, try a new approach on a co-worker, say Thank You more, sleep more, drink more water, etc.
The point: just enjoy and try :)
Love,
Jen
