If you have yet to read the Happiness Project blog, hop on over and check it out. She has such a wonderful way of summing up big, epic truths in life with a casual, humorous voice.
One of my favorite things about this site (and the book!) are her simple truths in life - things she has learned in her life that seem to apply universally. In this post, she talks about staying in the present using a scene from one of my favorite movies, Before Sunrise (don't judge! I grew up in the 90s - Ethan Hawk was dreamy then!).
