McMillan is here to reroute the way you think about love and relationships. What started off as a wildly successful Huffington Post article of the same name, "Why You're Not Married...Yet," is chock-full of quality relationship advice.

For those who struggle to find, and stay in, long-lasting relationships, McMillan breaks down the various ways women sabotage their relationships, and offers solutions. However, despite the tough-love titles of her chapters — including "You're a Bitch," "You're Shallow," and "You're a Slut" (ouch) — McMillan is a sympathetic friend who shares her own journey with finding love so that you can learn from her successes and mistakes.

"The Artist's Way" is a 12-week program designed to reignite one's creative passion and to recover a sense of connection, strength, and compassion (just to name a few). Each week, Cameron gives readers a new set of challenges and goals to nurture the artist — and human — within.

One of the cornerstones of the program is the practice of Morning Pages. Cameron prescribes a daily ritual of filling three pieces of paper with "longhand writing, strictly stream-of-consciousness" writing. The main point of this is to rid yourself each morning of all the negative, yucky thoughts that may plague you. By getting these down on paper, the hope is that you will free up the pathways of creativity, which are usually blocked by fear, self-doubt, and self-criticism.
